Hidden Desire Extreme Inflatable Ribbed Plug: review

Inflatable ribbed anal plug in silicone reviewed against the manufacturer’s own specifications, a dimension sketch, and packaging print, as well as price data from six Swedish stores. Insertable length 18.5 to 23 centimeters, diameter 4 to 5.5 centimeters, quick-release valve and 0.162 kilogram — but the manufacturer’s own cardboard box states 25 centimeters and 6 centimeters, and that difference is the whole point of this desk review.

My rating

An inflatable anal plug that does two things better than the category standard: it is silicone all the way through instead of latex, and the manufacturer lists both deflated and inflated measurements. At the same time it does one thing worse than it should — the manufacturer’s specification and the manufacturer’s own packaging list different maximum measurements; the base width is not published at all; and there are neither a waterproofing class, a warranty, nor spare parts. Count on 5.5 centimeters, not 6.

  • Insertable length 18.5–23 cm, diameter 4–5.5 cm
  • Silicone throughout the plug — not latex
  • Quick-release valve and T-shaped base
  • Weight 0.162 kg, package 28 × 9.5 × 6.5 cm
  • The packaging states 25 cm and 6 cm — the specification 23 and 5.5
  • 293–376 SEK at six stores for the same EAN

Hidden Desire Extreme Inflatable Ribbed Plug in brief

Hidden Desire Extreme Inflatable Ribbed Plug Advanced is an inflatable anal plug in silicone with a ribbed, tapered shape and a separate pump bulb connected to the plug via a hose. It is part of the EXTREME series by Hidden Desire, which the brand owner describes as a collection of inflatable anal products for those who want to push boundaries. The model is the smaller of two ribbed variants: Advanced, and Expert is significantly larger.

The specification according to the manufacturer looks like this: insertable length 18.5 to 23 centimeters, insertable diameter 4 to 5.5 centimeters, material silicone, weight 0.162 kilograms, packaging in a cardboard box measuring 28 × 9.5 × 6.5 centimeters, and country of origin China. The item number is 16855-BLACK, the model number is 16855, and the barcode is 8713221835246. The recommended retail price in the manufacturer’s own price list is 41.99 euro. In Sweden, the item is sold by six shops at prices between 293 and 376 SEK, and five of them have it in stock.

This review is exclusively about the black Advanced variant. It’s worth noting this right away, because the sister model Expert has a completely separate barcode (8713221835260) and almost twice the dimensions. Several Swedish shops sell both under similar-sounding names, and some also list them with different centimeter figures in the headline. Always check the barcode if you compare prices between shops.

The product has no electronics. There is no motor, no battery, no charging cable, no app, and no IP rating — the pump bulb is completely manual. This makes the specification short, but it also makes it easier to deal with: there are no operating times or charging times that could be misunderstood—just measurements, materials, and construction. These are also exactly the three points where the manufacturer’s own information turns out to differ, which is the single most important part of this text.

How does an inflatable anal plug work, technically?

The principle is simple and old. The plug is hollow and made from an elastic material. A hose runs from the base of the plug to a pump bulb that you squeeze with your hand. Each squeeze pushes a small volume of air into the plug, which therefore stretches out in all directions until the material’s elasticity balances the pressure. A one-way valve in the connection keeps the air in place between squeezes, and a release valve lets it out again.

In practice, this means the product has two completely different sizes depending on when you measure it. The manufacturer lists both end positions: 18.5 centimeters of insertable length and 4 centimeters in diameter in the deflated position, 23 centimeters and 5.5 centimeters at maximum inflation, according to the dimension diagram. It’s an increase in cross-section volume of roughly double, and the manufacturer’s packaging summarizes it with the text 200 % EXPANSION.

The difference from a fixed plug is fundamental, not just practical. A fixed plug has the circumference it has, and the fit is determined when you insert it. An inflatable plug is inserted in its smallest position and only expands afterwards, which shifts the entire load from the insertion to a gradual stretching you control yourself. What can be established is that it’s a design that gives the user control over the pace—and at the same time a design where the margin for error lies with the user rather than with the product, because nothing stops you from pumping longer than you should.

Starter, Advanced, or Expert — which Hidden Desire Extreme is which?

The EXTREME series by Hidden Desire includes several inflatable plugs that are easy to mix up, especially since Swedish shops often translate the names freely. This is what the four most closely related ones look like, according to the manufacturer’s own specifications.

  • Inflatable Smooth Plug Starter (item 16851) — smooth instead of ribbed, insertable length 10.5–14.5 cm and diameter 3–5.5 cm. Recommended price 31.99 euro.
  • Inflatable Butt Plug Advanced (item 16853) — short and wide, insertable length 12–14.5 cm and diameter 4.5–7 cm. Recommended price 41.99 euro.
  • Inflatable Ribbed Plug Advanced (item 16855) — the model this text is about. Ribbed, insertable length 18.5–23 cm and diameter 4–5.5 cm. Recommended price 41.99 euro.
  • Inflatable Ribbed Plug Expert (item 16857) — same shape, but significantly larger: insertable length 28–38 cm and diameter 5.5–6.5 cm. Recommended price 64.99 euro.

The pattern is clear when you line up the numbers next to each other. The series doesn’t vary primarily in how much the products expand, but in which direction they get bigger. Butt Plug Advanced is the widest of them all—seven centimeters in diameter versus Ribbed Advanced 5.5—but only 14.5 centimeters long. Ribbed Advanced is the opposite: long and relatively narrow. If you choose the wrong model because the names are similar, you don’t get a product that’s “a little smaller,” but a product with a completely different geometry.

Measurements: 18.5–23 cm and 4–5.5 cm — or 25 cm and 6 cm?

Here is the most important observation in the entire walkthrough, and it requires you to keep three different documents separate—documents that all come from the manufacturer itself.

The manufacturer’s specification table states an insertable length of 18.5 to 23 centimeters and an insertable diameter of 4 to 5.5 centimeters. The manufacturer’s own dimension sketch—shown as an image in the product gallery—repeats exactly the same figures with marked measurement lines: max Ø 5.5 cm, min Ø 4 cm, max 23 cm, min 18.5 cm. So two independent publications from the same source say the same thing.

The manufacturer’s printed packaging says something else. On the side of the carton it says MAX ø 6 CM, MIN ø 4 CM, MAX 25 CM and MIN 18.5 CM. The minimum length matches, but the maximum length is two centimeters longer and the maximum diameter is half a centimeter larger than in the specification and the sketch. This is not a shop that got it wrong—it’s the manufacturer’s own material that isn’t consistent.

Why the packaging and the specification sheet don’t say the same thing

The most likely explanation for the difference in length is that the two documents measure different things. The specification table is explicitly labeled “insertable length,” meaning the part that can be inserted. The dimension sketch line runs from the tip down to the underside of the T-shaped base. The packaging’s 25 centimeters could very well be the product’s total length, including the thickness of the base and the vent neck underneath. Two centimeters is a reasonable size for exactly that kind of difference.

The difference in diameter is harder to explain away. Six centimeters versus 5.5 centimeters is not a matter of where you start measuring—it’s a matter of how wide the material actually becomes at maximum inflation. What can be established is that this figure differs between two sources that are both the manufacturer’s own, and that the more cautious figure is found in the document that is labeled as the specification, while the more generous one is on the selling packaging. Base your assessment of whether the product fits you on 5.5 centimeters, not on 6. It’s the more cautious value, it’s what’s stated in the specification, and the manufacturer also explicitly warns against inflating past the specified maximum width and maximum height.

A third measurement is completely missing from both documents: the width of the base. The manufacturer does not publish a figure for how wide the T-shaped foot is, even though that is the measurement that determines whether the plug can slide in completely. None of the six Swedish stores provide it either. This is a real gap in the documentation for a product where the base is the safety-critical detail.

What the Swedish stores write—and what it means

The stores have chosen different sides in this conflict, and the result is that the same article number is marketed in Sweden with two different sizes.

Vuxenkul is the only store that correctly reproduces the manufacturer’s specifications. Their feature table lists a length of 23 cm and 18.5 cm, as well as a diameter of 4 cm and 5.5 cm — exactly the values from the dimension sketch. Instead, Vuxen, Blush Me, and SexleksakerOutlet reproduce the numbers from the packaging: total length 25 centimeters and a diameter of up to 6 centimeters. That’s why the product is called "25 cm" in three of the Swedish shop titles. Sexonic publishes no dimensions at all.

Joyland contradicts itself on one and the same page. In the running text, it says that the maximum diameter and length in inflated position are 6 and 25 centimeters respectively, while the shop’s own specification table further down states a diameter of 4 centimeters and an insertion length of 18.5 centimeters. Both pieces of information are reasonable on their own — one describes the inflated position, the other the deflated state — but they are left uncommented next to each other, and a reader who only sees the table gets the impression that the plug is four centimeters thick and nothing more.

The takeaway for you who are buying: count on a plug that is just under 19 centimeters insertable and four centimeters wide when you insert it, and that can be stretched to about 23 centimeters and 5.5 centimeters. If it turns out to be 25 and 6, that’s a bonus, not a starting point.

Weight: 0.162 kilograms — but of what?

The manufacturer lists 0.16 kilograms in the specification table and 0.162 kilograms in the product data behind the page. The figure is shown under the heading Additional Information along with the packaging dimensions, which suggests it’s a weight per sales unit rather than a net weight of only the silicone. The manufacturer does not specify whether those 162 grams refer to the plug alone or the plug with the hose, pump bulb, and cardboard, and none of the six Swedish stores publishes any weight at all.

Having a number to compare with still helps. The sister model Butt Plug Advanced is stated to weigh 0.25 kilograms despite being only 14.5 centimeters long — but it is, in return, 7 centimeters wide, meaning it has more material. The significantly longer Ribbed Expert is stated to weigh 0.18 kilograms. That a plug measuring 38 centimeters only weighs 18 grams more than one measuring 23 centimeters says something about how thin-walled this type of product is: most of the volume is air, even in the deflated state.

Material: 100 percent silicone, according to the manufacturer

The material question is the only characteristic of an intimate product that can’t be compensated for with habit or care, and for a product that is supposed to be stretched far beyond its resting shape, it is also a matter of strength. The manufacturer lists a single material in the specification table: silicone. In the product description, it is specified as 100 percent pure silicone, and the packaging bears the labeling 100 % SOFT-SILICONE.

What silicone means for a product that is supposed to be stretched

Silicone is a non-porous material. A non-porous surface can be cleaned, because there are no microscopic cavities where residue can get trapped. It is the single most important property of a material that is meant to sit against mucous membrane, and that is why the material declaration weighs more heavily than almost all other lines in a specification.

For an inflatable product in particular, two additional properties apply. The first is elasticity: silicone returns to its original shape after being stretched in a way that very few other materials can, which is the prerequisite for the plug to be pumped up and emptied hundreds of times without becoming permanently expanded. The second is temperature resistance, which means the product can withstand hot water during cleaning—something that is harder to take for granted with a latex alternative.

What makes the silicone choice especially relevant here is the contrast with what the category otherwise consists of. Inflatable anal plugs have traditionally been made of latex because latex is cheap and extremely stretchable. You2Toys Anal Expert, which is sold in the same Swedish stores, is an example: the manufacturer states that it is made of natural rubber latex, with an explicit notice that the material can cause allergy. Latex is also porous in that sense, meaning that its surface breaks down due to oil and UV light. So Hidden Desire choosing silicone for the entire plug is not a given in this category, but a clear differentiating feature.

Phthalates and material declaration—what it says and what it doesn’t

Phthalates are a group of plasticizers used to make plastic—above all flexible PVC—pliable. The Swedish Chemicals Agency describes them as substances that can affect the hormone system and make reproduction more difficult, and several of them are therefore restricted or banned within the EU in a large number of products. This product category in particular is subject to recurring supervision because it contains flexible plastic against skin and mucous membrane.

Silicone doesn’t require phthalate plasticizers to become soft—the softness comes from the polymer’s own structure—and therefore silicone as a material specification is, in itself, a better indication than almost any other entry in a product specification. The manufacturer, however, never prints the words phthalate-free, BPA-free, or latex-free for this item. The closest you get is the wording 100 percent pure silicone.

But the store Vuxenkul instead explicitly states that the silicone is free from phthalates and completely safe for the body. That is a store claim, not a manufacturer claim, and it should be read as the store’s interpretation of the material specification rather than as a declaration from whoever produced the product. In substance, the interpretation is reasonable—but if you want a formal commitment to rely on, it isn’t published.

The pump bulb, the hose, and the valve—the parts that aren’t covered by the material declaration

Here there is a gap that is easy to miss. The product consists of at least four parts: the plug itself, a hose, a pump bulb, and a vent valve. The manufacturer’s material specification is a single word—silicone—without any breakdown by part. From the manufacturer’s own product images, it appears that the valve housing at the pump bulb is made of a hard, glossy material with a push button, so it is not made of silicone.

Compare how another manufacturer in the same category formulates it. For CalExotics XL Silicone Inflatable Plug, the material is broken down: silicone in the plug, hose, and pump bulb, ABS in the vent valves. That’s a more useful declaration, because it tells you exactly which part is what. Hidden Desires’ only material line doesn’t provide the same information. The manufacturer does not publish what the valve housing is made of. In practice, it matters little for hygiene, because the valve is at the end of the hose and never comes into contact with the body—but it’s an example of how the brief specification conceals more than it reveals.

A final note about origin. The manufacturer lists China as the country of origin, and in the machine-readable product data behind the product page, Ningbo Dianai Plastic Co Ltd is listed as the manufacturing company. It’s unusual for a factory to be named so openly in this industry, and that in itself is a plus for traceability even if it doesn’t say anything about quality.

How the plug is used: insert, pump, release

The workflow is the same for all inflatable plugs and is controlled entirely by hand. The plug must be completely emptied before it is inserted—when it is emptied, it measures 4 centimeters in diameter, and that is the measurement the insertion has to be able to accommodate. After that, you squeeze the pump bulb until you reach the fill level you want, and before removing it you release the air via the valve so the plug returns to its narrowest shape.

That’s where the logic of the entire design lies—in the final point. An inflatable plug should never be taken out while it is inflated. That’s also why the valve’s function matters more than the plug’s shape: emptying is not a convenience, but a prerequisite for the product to be usable at all.

Quick-release valve—the most important detail in the design

The manufacturer highlights that the product has a quick-release valve, a so-called quick release valve, and describes it as a safety and comfort feature. Joyland repeats the same information and describes that the valve releases the air quickly. Vuxenkul puts it this way: with the quick valve, you can immediately release the pressure whenever you want to take a break or end.

The difference compared to a simple screw valve is noticeable in practice. A screw valve requires you to find and turn a small control, often with slippery fingers, and release the air slowly. A quick-release valve is pressure. What can be established is that the push-button design reduces the time between "I want to stop" and "the plug is emptied," and it’s reasonably the most important feature of the entire product.

The valve is located in the transition between the hose and the pump bulb—i.e., outside the body and within reach throughout use. The hose in the manufacturer’s images is long enough for the pump bulb to rest in your hand while the plug is in place. However, the manufacturer does not publish a figure for the hose length, which is another piece of information that would be easy to provide and that none of the shops also shows.

Base: why the T-shaped foot determines whether the product is safe

All anal products must have a base that is wider than the insertable part. The reason is anatomical and applies regardless of brand: the rectum has no natural stop, and a product without a sufficiently wide base can slide farther in than intended. The base is the only design detail that prevents this.

On this model, the base is T-shaped with two outward-swept arms rather than a round plate, which is clearly visible in the manufacturer’s product images. SexleksakerOutlet describes it as a wide base for safe use. The shape has a practical advantage in addition to the stop function: a T-shape lies flatter against the body than a circular flange when you sit or lie on your side.

What, on the other hand, cannot be controlled is how wide the base is in centimeters, since neither the manufacturer nor any of the shops publish this measurement. For a product that expands to 5.5 centimeters, that’s a task you would have liked to be able to compare with the plug’s maximum diameter. Here, you have to be content with noting that the base in the pictures is visibly wider than the plug’s thickest part in the emptied position.

What does 200 percent expansion mean?

The packaging bears the marking 200 % EXPANSION. The wording is marketing, not a measurement standard, and it’s worth calculating what it could possibly mean.

If you go by diameter, it doesn’t add up: from 4 to 5.5 centimeters is an increase of 37.5 percent, not 200. If you go by cross-sectional area, it gets closer—the area grows with the square of the diameter, i.e., by roughly 89 percent, which in everyday terms can be described as the plug being almost twice as thick in cross-section. If instead you calculate based on volume, where both the length and the cross-section increase, you end up in the range of a doubling, maybe a bit more than that. Interpreting "200 percent" as "twice as large" is therefore defensible for volume but misleading for width.

The score is practical rather than mathematical. The number that matters when you judge whether the product fits you is 5.5 centimeters, not 200 percent. A percentage value without a specified size can’t be compared between manufacturers, while millimeters can.

Safety: the limits the manufacturer sets itself

This product category has a safety profile that’s different from almost everything else in a sex toy assortment, and the manufacturer is unusually straightforward about it.

Overpressure and the manufacturer’s own warning

On the product page, there is an explicit disclaimer: the product may not be inflated beyond the stated maximum width and height to avoid damage to the product, and contact with sharp objects should be avoided. Vuxenkul presents the same meaning in Swedish and adds that overpressure can harm both the user and the toy.

There is no mechanical stop that stops you at 5.5 centimeters. The inflation bulb keeps working, and the only thing that indicates where the limit is is the number in the specification. Practically speaking, that means two things. First, the contradictory max diameter information—5.5 centimeters in the specification versus 6 on the package—is not an academic issue; it’s the difference between two different stop limits. Second, counting inflation presses is a useful habit: once you’ve found a position that works, the number of presses is the only measuring tool the product has.

A second safety aspect is the one that applies to all anal products, regardless of manufacturer. Never go directly from anal to vaginal use without cleaning in between, and avoid sharing the product between people without cleaning it properly. On a product with a hose and valve, there are also more surfaces than usual that you need to clean.

Which lubricant works with a silicone plug?

Water-based. Silicone-based lubricant should not be used on silicone products—it breaks down the silicone surface over time and makes it porous, and a porous surface can’t be cleaned properly anymore; it’s only a matter of replacing it. On an inflatable product, this is especially serious, because the surface also has to stretch: a weakened silicone surface is a surface where a crack can occur exactly where the material is under the most load.

Oil-based products like coconut oil or massage oil leave a film that’s hard to remove and that collects residue. Anal use also requires plenty of lubricant as a prerequisite, not an added option, since the rectal mucosa doesn’t produce anything on its own. A thicker, gel-like water-based lubricant stays in place longer than a thin, runny one and is generally the practical choice for this type of product. The manufacturer doesn’t publish its own lubricant recommendation for the item.

Cleaning, storage, and lifespan

An inflatable plug takes more work to take care of than a solid one, and that’s a real downside worth knowing before you buy it.

How is an inflatable anal plug cleaned?

Rinse the plug in lukewarm water and wash it with an unperfumed soap or a cleanser intended for intimate products directly after use. Silicone’s non-porous nature makes the plug itself easy to clean.

Two parts require extra consideration. The first is the valve housing and the pump bulb, which should not be submerged in water more than necessary — the manufacturer does not publish an ingress protection rating or any information stating that the product is waterproof, and in the absence of such information, a product should be treated as not waterproof. The lack of a rating is never a sign that the product would be approved for submersion.

The second is the seam where the hose meets the plug’s base. It’s a physical seam, unlike on a solid plug that’s molded in one piece, and residue collects in seams like these. Wipe it off especially thoroughly and let the product air-dry completely before putting it away. The manufacturer does not state whether the product can be boiled, and an inflatable design with air enclosed in a sealed chamber should under no circumstances be placed in boiling water — the air inside the plug expands from the heat.

Storage and what breaks first

Store the product empty, dry, and separated from other silicone products. Two silicone surfaces that stay in contact with each other for a long time can stick to each other. The manufacturer expressly warns against contact with sharp objects, which is especially relevant here: a small hole in a solid plug is cosmetic damage, while a small hole in an inflatable plug makes it unusable.

What can be established about the lifespan is that it’s determined by three things, all of which are outside the plug’s silicone: the valve’s seal, the hose connection, and the number of inflation cycles. A one-way valve that starts to leak causes the plug to collapse during use, and it’s the most common failure mode for the entire product type. The manufacturer does not sell replacement parts for the item and does not publish any information about replacement valves or replacement hoses. Once the valve goes, the product is, in practice, used up.

No storage pouch is stated to be included. The manufacturer’s packaging image lists the contents as the plug including pump bulb — the text INCLUDING: BULB is printed on the cardboard — and nothing else. The cardboard measures 28 × 9.5 × 6.5 centimeters and is a standard retail package with a hanging hole, so it is not a storage solution.

Hidden Desire Extreme Inflatable Ribbed Plug compared with the alternatives

Five comparisons are relevant: three against the sister models in the same series, one against the cheaper latex alternative, and one against a silicone plug from another brand. All the information below comes from each respective manufacturer’s own specifications.

Against Hidden Desire Extreme Inflatable Ribbed Plug Expert

Expert is the same product in a completely different size class. The manufacturer states insertable length of 28 to 38 centimeters and insertable diameter of 5.5 to 6.5 centimeters, versus Advanced’s 18.5 to 23 centimeters and 4 to 5.5 centimeters. That means that Expert’s smallest diameter is as large as Advanced’s largest diameter, and that Expert’s smallest length is five centimeters longer than Advanced’s maximum.

The recommended shop price from the manufacturer differs by 23 euros: 64.99 versus 41.99. Weight differs by only 18 grams, 0.18 versus 0.162 kilograms, which confirms that the difference is in volume rather than in the amount of material. The package is 10.5 centimeters longer, 38.5 versus 28 centimeters.

So the choice between them is not about one being an upgrade of the other. Advanced can be inserted at four centimeters; Expert starts where Advanced ends. If you’re unsure, you should not buy Expert as “a little more to grow into,” because the entry size is completely different.

Against Hidden Desire Extreme Inflatable Smooth Plug Starter

Starter is the series’ entry model: insertable length 10.5 to 14.5 centimeters, insertable diameter 3 to 5.5 centimeters, smooth instead of ridged, recommended price 31.99 euros. Note that the maximum diameter is exactly the same as on Advanced — 5.5 centimeters — but that the starting diameter is a full centimeter smaller, and that the plug is a little over eight centimeters shorter in its inflated position.

That makes Starter the obvious choice for anyone who’s unsure whether this product type works. You’ll reach the same final width, but from a significantly smaller entry point and with a shorter insert depth. The smooth surface also has a practical advantage: fewer seams and ridges to clean.

What Advanced adds is the ridges and the length. The ridged profile provides a step-by-step, distinct feel during insertion and movement instead of a smooth cone, which is the whole point of the model. If you don’t want that structure, there’s no reason to pay ten euros more in the recommended price.

Against Hidden Desire Extreme Inflatable Butt Plug Advanced

This comparison shows most clearly how different the series is despite similar-sounding names. Butt Plug Advanced costs exactly the same in the recommended price — 41.99 euros — but has insertable length of 12 to 14.5 centimeters and insertable diameter of 4.5 to 7 centimeters. So it’s 8.5 centimeters shorter but 1.5 centimeters wider at full inflation, and with 0.25 kilograms it weighs almost 90 grams more.

Two products for the same price, from the same series, with the same word Advanced in the name, but with a 1.5-centimeter difference in maximum diameter and an 8.5-centimeter difference in maximum insertable length—each in its own direction. It’s exactly the kind of situation where it pays to read the specifications instead of the headline. If you want width, it’s the Butt Plug Advanced model; if you want length and ridges, it’s the Ribbed Plug Advanced.

Against You2Toys Anal Expert—what’s the difference between silicone and latex?

You2Toys Anal Expert is the cheaper option in the same Swedish shops and one of the best-selling inflatable plugs of all time. The manufacturer states 13 centimeters in length and Ø 2 to 4 centimeters that can be inflated up to 9 centimeters. The material is latex, made from natural rubber latex, with an explicit notice from the manufacturer that it may cause allergies.

In terms of width, it goes further: nine centimeters versus Hidden Desires 5.5. At the same time, it is ten centimeters shorter in the inflated state and starts narrower, by two centimeters versus four. These are two completely different usage profiles—the one is based on an extreme width increase from a very small entry point, the other on a longer plug with moderate expansion.

The material difference is the one that weighs heaviest in an assessment. Latex is cheaper and more stretchable, but latex allergy causes reactions on the mucous membrane faster than on normal skin, and an intimate product is exactly the kind of use where the information matters. Latex also breaks down from oil and ages even when unused. Silicone has none of those weaknesses. So the fact that the Hidden Desire model costs more per centimeter of expansion is not the whole picture: you’re paying for a material that lasts longer and that more people can use.

Against CalExotics XL Silicone Inflatable Plug

CalExotics XL Silicone Inflatable Plug is a silicone competitor in a higher price range—58.99 euro in the recommended price versus 41.99. The manufacturer states total length 16 centimeters, insertable length 16 centimeters, and insertable diameter 4.5 centimeters, as well as the weight 0.19 kilogram.

Two things stand out in the comparison. The first is that CalExotics lists one diameter value, not an interval—it’s the starting diameter, and how far this model expands isn’t published in the same way. Hidden Desire shows both end positions, which is more information, even if the information we’ve seen isn’t entirely consistent between the manufacturer’s own documents.

The second is the material breakdown, where CalExotics is clearer: silicone in the plug, the tube, and the pump bulb, and ABS in the air-vent valves. Hidden Desire only states silicone. On price and the stated end positions, Hidden Desire wins; on material breakdown per part, CalExotics wins.

Price range: 293 to 376 SEK and five stores with stock

Sex Swedish stores sell the item with EAN 8713221835246. The lowest price is Vuxenkul at 293 SEK, and the highest price is Sexonic at 376 SEK. That’s 83 SEK, or a 28 percent difference, for the exact same product number, same color, and same packaging.

The stock situation is unusually good for this category. Five of the six stores had the product in stock at the price check: only Sexonic, which is also the most expensive, was missing it. That means the price spread is actually relevant here, unlike many products where the cheapest stores are sold out. Among the stores with stock, the range goes from 293 SEK at Vuxenkul to 336 SEK at Joyland — 43 SEK, or just under 15 percent.

The difference between the two cheapest is, in practice, nonexistent: Vuxenkul 293.00 SEK and Vuxen 293.30 SEK. Blush Me and SexleksakerOutlet are both at 299 SEK. So the pricing is tightly clustered around the three-hundred-kronor mark, and it’s only Joyland and Sexonic that deviate upward. Several of the stores list 419 SEK as the regular price in their product feeds at the same time, which means that the price you see today is a promotional price at the majority of them.

One final note about the total cost: shipping costs can change the ranking in this price range. The stores’ product feeds show shipping fees from zero SEK to just under a hundred SEK per order in this size, and for an item that costs under 350 SEK it’s a difference that’s larger than the entire price spread between the stores. Always check the final total in the checkout.

Who is it for — and who isn’t it for?

It’s for you if you already have experience with anal products in the four-centimeter range and want a product where you control the size during use instead of choosing it when you buy. It’s for you if you want silicone instead of latex, if you prefer a ridged profile over a smooth cone, and if you want a longer insertion depth than a classic buttplug provides. The quick-release valve also makes it a more reasonable choice than older designs with a screw valve.

It’s not for you if you’re new to anal products. Four centimeters in diameter in the emptied position isn’t an entry size — that’s where the series’ Starter model with three centimeters is the sensible option, and it also costs less. It also isn’t for you if you want the biggest possible width increase: You2Toys Anal Expert goes up to nine centimeters, so far beyond this model’s 5.5.

It doesn’t suit you if you want as little maintenance as possible. A plug with a hose, a valve, and a pump bulb has more surfaces and a connection that a molded plug lacks, and it can’t be submerged in water because no ingress protection (IP) rating is published. And it doesn’t suit you if you require the manufacturer’s figures to be unambiguous before you buy—here, the maximum length and maximum diameter differ between the manufacturer’s specifications and the manufacturer’s own packaging, and the base width is not published at all.

Warranty claims, and the right of withdrawal

The manufacturer does not publish any consumer warranty for this item. Hidden Desire is sold via SCALA, which is a wholesaler aimed at retailers, and their product page includes neither a warranty period, warranty terms, nor any satisfaction guarantee. There is therefore no optional manufacturer warranty to rely on, unlike what is common with electronics-heavy brands in adjacent categories.

What always applies, however, is your statutory rights, and they are independent of what the manufacturer promises. Under the Swedish Consumer Sales Act (konsumentköplagen), you have three years of right to complain for faults with the product. An initial fault with a valve that doesn’t seal, or a seam in the silicone that comes loose during normal use, is exactly the kind of thing that’s covered—and since the product lacks a manufacturer warranty, the right to complain is the only protection you have. Save your receipt.

For distance purchases, you also have a right of withdrawal for fourteen days under the Swedish Law on distance contracts and contracts outside business premises (lagen om distansavtal och avtal utanför affärslokaler). Be aware that, in practice, the right of withdrawal is limited for hygiene products that have been taken out of a sealed package. This product is sold in a carton, and an opened carton generally means the right of withdrawal can no longer be used. The right to complain about faults, however, always applies. If you have questions about what applies in your case, Konsumentverket (the Swedish Consumer Agency) advises you via Hallå konsument.

Frequently asked questions about Hidden Desire Extreme Inflatable Ribbed Plug

How big is the Hidden Desire Extreme Inflatable Ribbed Plug, really?
The manufacturer’s specifications and the manufacturer’s own dimension diagram both state an insertable length of 18.5 to 23 centimeters and an insertable diameter of 4 to 5.5 centimeters. The manufacturer’s printed packaging, however, states a maximum of 25 centimeters and a maximum of 6 centimeters in diameter, with the same minimum values. The difference in length can be explained by the fact that the packaging likely indicates the total length including the base, while the specification indicates the insertable length. The half-centimeter difference in diameter cannot be explained in the same way. Assume 5.5 centimeters, which is the more cautious value and the one stated in the specification—not least because the manufacturer warns against pumping past the stated maximum measurement.
Why is the product called 25 cm in Swedish stores when the manufacturer writes 23 cm?
That’s because the Swedish stores have taken the number from the packaging instead of from the specification sheet. Vuxen, Blush Me, and SexleksakerOutlet all list total length as 25 centimeters and a diameter of up to 6 centimeters, which are the packaging values. Vuxenkul is the only Swedish store that correctly reproduces the manufacturer’s specification with 18.5 and 23 centimeters as well as 4 and 5.5 centimeters. Joyland lists both sets of values on the same page: 6 and 25 centimeters in the running text and 4 centimeters and 18.5 centimeters in its own specification table. It’s the same item with the same EAN in all cases.
What’s the difference between Advanced and Expert?
The size—and it’s significant. Advanced (item 16855, EAN 8713221835246) has an insertable length of 18.5 to 23 centimeters and a diameter of 4 to 5.5 centimeters. Expert (item 16857, EAN 8713221835260) has an insertable length of 28 to 38 centimeters and a diameter of 5.5 to 6.5 centimeters. So Expert’s smallest diameter is the same as Advanced’s largest diameter, and Expert’s smallest length is five centimeters longer than Advanced’s maximum. The recommended store price differs by 23 euros. Expert is not an upgrade but a different size class with a completely different entry size.
Is Hidden Desire Extreme Inflatable Ribbed Plug made of silicone or latex?
Silicone. The manufacturer states the material as silicone in the specification table, as 100% pure silicone in the product description, and as 100% soft silicone on the packaging. This is a real difference compared with the category’s most common alternative: You2Toys Anal Expert, which is sold in the same Swedish stores, is stated by its manufacturer to be made of natural rubber latex, with an explicit note that the material can cause allergies. Silicone is non-porous, tolerates hot water, and does not break down from oil in the same way as latex. However, note that the manufacturer does not specify the material for the plug, the tube, the pump bulb, and the valve separately—the valve housing, judging from the manufacturer’s pictures, is not silicone.
Is it waterproof, and can it be used in a shower or a bathtub?
The manufacturer does not publish any enclosure rating and no information about water resistance for this item, and none of the six Swedish stores does either. In the absence of a rating, a product must be treated as not water-resistant. Of course, the silicone plug itself can be rinsed during cleaning, but the pump bulb and the valve housing should not be submerged in water. The lack of an IP rating is never a sign that the product would be approved for submersion—it only means that it has not been tested for it.
How is an inflatable anal plug cleaned?
Rinse the plug in lukewarm water and wash it with fragrance-free soap or a cleaning product intended for intimate products right after use. The silicone is non-porous and therefore easy to clean. Two areas require extra care: the joint where the hose meets the plug’s base, because it is a physical joint where residue can collect, and the valve housing, which should not be submerged in water because no enclosure rating is published. Let the product air-dry completely and store it deflated, dry, and separated from other silicone products. Never put it in boiling water—the air trapped inside the plug expands from the heat.
Which lubricant should I use?
Water-based, and generously. Silicone-based lubricants should not be used on silicone products, because they break down the surface over time and make it porous. On a product that also needs to be stretched, it’s not just a hygiene problem but also a strength issue, because a weakened surface gives way exactly where the load is greatest. Oil-based products such as coconut oil leave a film that is difficult to remove. Anal use requires lubricant as a prerequisite and not as an optional extra, because the anal mucosa does not produce any of its own. The manufacturer does not publish any lubricant recommendation for the item.
What about warranty and complaints?
The manufacturer does not provide any consumer warranty for this item—there is no warranty period, no warranty terms, and no satisfaction guarantee listed on the product page. What applies instead is your statutory rights: a three-year right to complain for defects in the goods under the Swedish Consumer Sales Act (konsumentköplagen), and a fourteen-day right of withdrawal for distance purchases under the Act on Distance Contracts and Contracts Outside Business Premises (lagen om distansavtal och avtal utanför affärslokaler). Since there is no manufacturer warranty, your right to complain is your only protection, so save the receipt. Be aware that in practice the right of withdrawal is limited for sealed hygiene products that have been opened—however, the right to complain for defects always applies. Konsumentverket (the Swedish Consumer Agency) provides guidance via Hallå konsument.

I run the site myself and have reviewed 395 products since 2023. Before that, I worked for eight years as a buyer of intimate hygiene products, and that’s where the product knowledge comes from. Each review is based on the manufacturer’s own specifications, product data sheets, and price data from all the shops that sell the product — all sources are at the very bottom of the page and can be checked. I compare the models against each other based on what can actually be verified: materials, dimensions, intensity levels, water-resistance rating, warranty, and price. If you find an error, I want to know about it.
