Hidden Desire Extreme XXL Anal Serpent 45 cm: review

Hidden Desires longest spiral dildo reviewed against the manufacturer’s own specifications, the brand owner’s catalog listing, and price data from eight Swedish retailers. Total length 45 centimeters, insertable diameter 3.5 centimeters, weight 0.61 kilograms, and smooth PVC — but no phthalate declaration, no manual, no warranty period, and three stores that state the wrong diameter.

My rating

A one-piece molded PVC dildo that’s 45 centimeters long with an even diameter of 3.5 centimeters, a continuous spiral rib, and a flared base disc. The dimensions are well substantiated: the manufacturer lists them both in the catalog and in the company’s own product image, and Taboos weight information confirms the 0.61 kilograms. What’s missing is the rest of the documentation — no insertable length, no base measurement, no phthalate declaration, no manual, and no warranty period. Three of the eight stores also state the wrong diameter. The price from 212 SEK is the lowest across the entire model family.

  • Total length 45 cm, insertable diameter Ø 3.5 cm according to the manufacturer
  • Weight 0.61 kg — confirmed by Taboos 608 g
  • Smooth PVC, one-piece molded, flared base disc as a stopper
  • No phthalate declaration, no manual, and no warranty period
  • Three stores state the wrong diameter: 3 cm and 4 cm respectively
  • 212–399 SEK at eight stores for the same EAN

Hidden Desire Extreme XXL Anal Serpent 45 cm, in brief

Hidden Desire Extreme XXL Anal Serpent is a 45-centimeter-long, spiral-patterned anal dildo in PVC with a flared base. It is part of what the manufacturer calls XXL Anal Gear — a series where the whole point is the length rather than the girth. The manufacturer’s item number is 16881, the SKU is 16881-BLACK, and the barcode is 8713221835727. The list price is 35,99 euro, and in Sweden the item is sold by eight stores at prices between 212 and 399 SEK.

The specification is short, and that in itself is part of the picture. The brand owner SCALA 2.0 BV publishes the total length of 45 centimeters, insertable diameter of 3,5 centimeters, the material PVC, the weight 0,61 kilo per unit, the packaging type polybag, and the country of origin China. The manufacturer’s own web store states the length, the material and the wide base — but neither the diameter, weight nor any measurement of the base. There is no manual, no care instructions, and no warranty period.

This review is about the black variant with EAN 8713221835727. The product is sold only in black, and there are no color or size variants under the same item number — however, there are two closely related sister models that are easy to confuse with it, and that are covered further down.

What a 45-centimeter-long spiral dildo actually is

What sets this product category apart from standard anal plugs is the ratio between length and girth. An anal plug is short and wide: it’s meant to stay in place and it’s meant to spread. Anal Serpent is the opposite — narrow and extremely long. The manufacturer’s size image for item 16881 puts the numbers directly into the picture: 45 centimeters total length and a diameter of 3,5 centimeters. So the ratio is roughly 13 to 1 between length and thickness.

The shape is the same all the way from the tip to the base. The top is tapered and rounded; the shaft is patterned with a continuous spiral rib all the way down, and at the very bottom the shaft narrows toward a neck before it transitions into a round, flat base disc. There is no thickening in the middle and no clear waist in the shaft. In practice, the diameter is essentially constant from just below the tip to the neck.

In practice, this means that the product does not work as a size scale in the way a conical anal plug does. On a cone, you choose how far you go and get a new diameter for each centimeter. Here you get the same diameter regardless of how deep you go, and the only thing you vary is depth. It’s a much narrower product than it looks in the picture — 3.5 centimeters is about one third of the thickness of Hidden Desires’ own XXL cones — but it goes in further than almost any other product category.

The manufacturer describes the use as the product gliding in and then working it up and down. The base is stated to be wide for safety and comfort. That’s the entire instruction: Hidden Desire does not publish any user manual for its non-electrical anal products, which is confirmed by the company’s manuals page only listing vibrating anal plugs, masturbators, cock cages, sex swings, sex machines, electro products, and dolls.

Serpent, Snake, or the 35-centimeter version — which is which?

Three items from the same series are so close to each other in name and size that Swedish stores regularly mix them up. All three are in the SCALA catalog with their own model numbers and their own EAN numbers:

  • Extreme Anal Serpent 45 cm — model number 16881, EAN 8713221835727. This product. Total length 45 cm, insertable diameter 3.5 cm, weight 0.61 kg, list price 35.99 euro.
  • Extreme Anal Snake 45 cm — model number 16879, EAN 8713221835703. Same length, but narrower: insertable diameter 3 cm and weight 0.54 kg. Same list price, 35.99 euro.
  • Extreme Anal Serpent 35 cm — model number 16880, EAN 8713221835710. Same diameter as this model, 3.5 cm, but ten centimeters shorter and 0.49 kg. List price 29.99 euro.

So the difference between Serpent and Snake is therefore half a centimeter in diameter, not the length — even though the names suggest different product sizes. It’s worth checking the EAN number before you buy, since several Swedish stores sell both 45-centimeter models under almost identical headings. Five Swedish stores list Anal Snake 45 cm, and the cheapest of them is priced at 212 SEK — exactly the same price as the cheapest Serpent.

Measurements: 45 centimeters, Ø 3.5 centimeters — and stores that say otherwise

The length is the only measurement that all sources agree on. The manufacturer’s product page, the SCALA catalog, the manufacturer’s size chart, and all eight Swedish stores state 45 centimeters. That’s where the agreement ends.

The diameter: 3, 3.5, or 4 centimeters?

The manufacturer states 3.5 centimeters in two independent places: in the SCALA catalog’s field for insertable diameter and as a specified measurement in the manufacturer’s own product image 16881_BLACK_01. So that is the number that applies. Three of the Swedish stores state something else, and they furthermore do not state the same thing. Vuxen and Blush Me both write a maximum diameter of 3 centimeters. Joyland states 4 centimeters. Vuxenkul, Lekosmek, and Taboo stick to the manufacturer’s 3.5.

The variation isn’t academic. The difference between 3 and 4 centimeters in diameter is a difference of roughly 78 percent in cross-sectional area, and it’s the area — not the diameter — that determines how much the tissue needs to be stretched. If two stores underestimate the measurement and one overestimates it, a buyer who trusts the store information can end up with a product that is either noticeably thicker or noticeably thinner than expected. Start from the manufacturer’s 3.5 centimeters and treat the store figures as roundings in the wrong direction.

The base’s diameter is not published at all. Neither the manufacturer nor any of the stores states how wide the base plate is, even though it is the measurement that determines whether the product actually works as a stop. The manufacturer’s own images show a round, clearly flared base plate that is several times wider than the shaft, but there is no published measurement of it anywhere.

Insertable length: the figure the manufacturer does not publish

The manufacturer states total length, not insertable length. On a product whose entire reason for being is depth, it’s a conspicuous gap in the specification. The only source that puts a number on it is the retailer Joyland, which states an insertable length of 40 centimeters — meaning five centimeters less than the total length, which roughly corresponds to the neck and the base plate. That is a store figure, not a manufacturer figure, and it should be read as a reasonable estimate rather than a measured value.

The comparison is interesting here. XR Brands, which sells a directly corresponding product under the name Hosed 18 Inch Swirl Thin Anal Snake, lists both measurements separately: 19 inches total length and 18 inches insertable length, i.e. 48.3 and 45.7 centimeters respectively. That an American manufacturer in the same price range can manage to distinguish between total length and insertable length, but Hidden Desire does not, says something about how thin the documentation is in this part of the market.

Weight: 0.61 kilograms and what it means

The SCALA catalog states the weight per unit as 0.61 kilograms. The manufacturer’s own web store doesn’t: the weight field in the product data is set to zero, which is the default value when a shop doesn’t fill in the information. Of the eight Swedish stores, only Taboo publishes a weight, and it lists 608 grams—practically identical to the manufacturer’s 0.61 kilograms. That’s unusual: in this product category, store weights are more often contradictory than consistent.

Six hectograms on a 45-centimeter-long and 3.5-centimeter-wide product means the material is solid all the way through, not hollow. You can work it out: a straight cylinder with a diameter of 3.5 centimeters and a length of 45 centimeters has a volume of roughly 433 cubic centimeters, and soft-form PVC typically falls around 1.2 to 1.4 grams per cubic centimeter. Solid PVC in that shape would therefore weigh on the order of about half to seven hectograms—which matches the manufacturer’s information and suggests a molded product without voids.

Practically speaking, the weight does two things. The product hangs noticeably under its own weight when you hold it at one end, and it’s too heavy to stay in place by itself in a use where you let go. It reinforces the impression that this is a product that’s controlled by hand from start to finish, not one that’s carried.

Material: smooth PVC—and what the manufacturer doesn’t say

The manufacturer lists a single material: smooth PVC. The SCALA catalog repeats PVC without any specification. None of the sources states which softener is used, what shore hardness the material has, or whether the product is free from phthalates.

PVC versus silicone—the difference that determines hygiene

PVC and silicone behave completely differently in this type of use, and the difference only becomes visible after some time. Silicone is non-porous: the surface has no microscopic cavities where residue can get stuck, which is the whole reason silicone products can be cleaned in a controllable way. Soft-form PVC has a surface that’s denser than TPE but not as insensitive as silicone, and it ages as the plasticizer slowly migrates out of the material.

What can be established purely from practical experience is that a PVC product is a consumable in a way that a silicone product isn’t. Over time, the surface becomes sticky or dull when the plasticizer migrates out, and once that happens the surface can’t be restored—only replaced. That points to treating the product as something with a definite lifespan rather than as an investment.

PVC has two specific, concrete advantages in this particular form. The first is that the material can handle both water-based and silicone-based lubricants, which silicone does not—and for a 45-centimeter-long product, choosing a lubricant is not a detail. The second is manufacturing economics: an injection-molded PVC product in this size can be sold for around two hundred kronor, while the corresponding one in platinum silicone would be about an order of magnitude higher.

Phthalates: why the lack of a declaration is a problem

Phthalates are a group of plasticizers used specifically to make PVC flexible. Kemikalieinspektionen describes them as substances that can affect the hormone system and make reproduction more difficult, and several of them are restricted or banned within the EU in a large number of products. Softened PVC against mucous membranes is precisely the use where the issue is relevant.

Hidden Desire does not publish a phthalate declaration for this product, either on the product page or in the brand owner’s catalog listing. The material description stops at the word PVC. It is not the same thing as saying that the product contains regulated phthalates—it only means that the manufacturer makes no commitments at all on the matter, and that a buyer therefore has nothing to go on.

Two Swedish stores fill the gap in on their own. Blush Me writes "Phthalate-free PVC", and Lekosmek and Taboo write "body-safe PVC". None of those wordings come from the manufacturer, and neither of the stores states where the information comes from. Compare this with XR Brands, which writes out phthalate-free PVC in its own product specification for the corresponding model—there, it is the manufacturer itself backing the claim, which is a completely different situation than when a retailer adds it to a product text.

The conclusion is cautious but still useful: assume this is softened PVC without a published declaration, use plenty of lubricant so the material doesn’t need to sit dry against the mucous membranes, and wash the product before first use. If you want a written phthalate undertaking from the manufacturer, you can find it with the competitor, not here.

The base, the spiral, and how the product is intended to be used

Hidden Desire describes the use in two sentences: the product slides in, and then you work up and down toward orgasm. The base is said to be broad for safety and comfort. There is no manual, no safety leaflet, and no warning text. Everything else that is stated about use comes from the stores, and they say partly different things.

Broad base or suction cup? The manufacturer and Joyland say different things

The manufacturer’s wording is "a wide base for safety and comfort", meaning a wide base. Joyland goes further and states that the base is a suction cup. The suction cup function is a store claim, not a manufacturer claim. The manufacturer’s own product images show a round, flat base plate with an even underside—a shape that very well could adhere to a smooth surface, but Hidden Desire does not promise that.

The difference matters for how the product can be used. A base that is only wide is a stop: it prevents the product from sliding all the way in, but it adheres to nothing. A suction cup also makes it possible to mount the product to the floor, wall, or shower and use it hands-free. If you want that feature guaranteed, you should choose a product where the manufacturer spells it out—XR Brands explicitly states a suction-cup base that "anchors to most flat surfaces" for its corresponding model.

What can be established regardless, though, is that the base is the only safety feature on the product. On a 45-centimeter-long, narrow and heavy toy, the base plate is what makes the difference between a product and an emergency visit. Never use an anal toy without a stop, and check the base plate for cracks before every use—PVC becomes more brittle at the neck over the years, and the neck is the most heavily loaded point on the entire product.

What the spiral pattern does

The spiral runs like a continuous raised rib along the entire shaft. The manufacturer says nothing about what it’s for beyond the fact that the product is smooth PVC. The stores describe it as a texture that provides rotating stimulation with every movement, and Joyland lists the surface as "ridged" and the firmness as "medium"—the only firmness-related claim that has been published for the product at all, and even that is a store claim.

From a purely geometric standpoint, the effect is easy to describe. A smooth shaft provides a consistent sensation in the axial direction; a spiral rib means that every in-and-out motion also delivers a continuous series of raised ridges that pass the same point. The rib is also continuous rather than broken up into beads, which means the resistance is even instead of coming in steps. Compare it with the sister model Anal Snake, which is half a centimeter narrower but otherwise built the same way, and with XR Brands bead versions, where the pattern is instead split into distinct beads.

A practical consequence of the spiral is that the surface is harder to wipe clean than a completely smooth shaft. The rib creates a continuous groove along the entire product where both lube and water stay put. This isn’t a hygiene problem by itself, but it means the product takes longer to get really dry, and a PVC product that’s put away damp in a sealed bag is worse off than one that’s left to air-dry.

Deep penetration: what actually limits it

Here’s a note that belongs here—something neither the manufacturer nor any of the stores does. The product is 45 centimeters long, and Joyland states 40 centimeters as insertable. It’s significantly longer than the rectum, which in adults is about 12 to 15 centimeters, and a product of this length therefore goes beyond it and into the sigmoid colon—the part of the large intestine that turns sideways. It’s not a straight channel, and it isn’t designed to pass straight objects.

There is no source from the manufacturer that says anything about this. Hidden Desire publishes no manual, no warning text, and no recommended insertion depth for the product, and the SCALA catalog doesn’t do it either. Selling a product in a certain length is not a claim that the entire length should be used. What can be established is that the depth is determined by the user, that nothing in the product limits how far it goes in other than the base plate, and that this is a product for someone who already knows what the body can handle—not one to experiment your way to the limit with.

Lubricant: the only question where PVC is easier than silicone

Joyland recommends a water-based lubricant. Taboo writes that the product is compatible with common lubricants, and Lekosmek writes that the material is compatible with most lubricants. The manufacturer itself says nothing at all about lubricants, which follows from the fact that there is no manual.

What can be established at the material level is that PVC doesn’t have silicone’s weakness. Silicone-based lubricants break down silicone surfaces over time and make them porous, and that’s why all silicone products come with the same warning. PVC isn’t affected in that way, and XR Brands explicitly writes in its own specification for the corresponding PVC model that it works with both silicone- and water-based lubricants.

That’s a real advantage of this particular product. Water-based lubricants dry out and need to be reapplied, and on a toy that’s supposed to pass 40 centimeters, it isn’t a matter of convenience—it’s a prerequisite for it to work at all. Silicone-based lubricant stays smooth for significantly longer. Oil-based products, on the other hand, are a poor choice regardless of material: they leave a film that’s difficult to remove and that can break down latex if a condom is used.

Cleaning, storage, and lifespan

Because there are no care instructions from the manufacturer, you follow what generally applies to non-electrical PVC products. Rinse the entire product in lukewarm water with fragrance-free soap or a cleaning product intended for intimate products, right after use. Be especially careful in the spiral groove and at the transition between the handle and the base plate, where lubricant collects. Let it air-dry completely before putting the product away.

Taboo’s IPX5 claim—a claim that doesn’t exist

One of the stores states that the product is waterproof according to the ingress protection rating IPX5. That information has no counterpart with the manufacturer, and it is also meaningless for this product. IP ratings according to IEC 60529 describe how well an enclosure protects electrical equipment against penetrating water. Anal Serpent is a one-piece molded cast of plastic with no electronics, no battery, and no enclosure. There is nothing to protect, and therefore nothing to classify.

The result is simple: the product can be rinsed in its entirety and used in the shower or bathtub without any classification being necessary. But a buyer who sees "IPx5" in a store table should know that the number is the store’s own added entry in a field that doesn’t belong with this type of product—not a value that the manufacturer has allowed to be tested.

How PVC ages—and when it’s time to replace it

A PVC product doesn’t wear out the way a silicone product does. It keeps its shape but changes on the surface when the plasticizer migrates out, and that process speeds up with heat, in sunlight, and with contact with oils. Practical signs to look for are that the surface becomes sticky or matte, that the material feels stiffer at the neck and base, or that small cracks appear where the shaft meets the baseboard.

Two things shorten the lifespan more than anything else. The first is heat: never boil a PVC product and never put it in the dishwasher. The second is storage in contact with other soft-plastic products—plasticizers travel between materials, and two PVC toys that lie against each other in a drawer can melt together at the contact surface over time. Store the product dry, cool, dark, and by itself. With that treatment, it’s the baseboard’s neck—not the surface—that normally sets the limit.

Documentation: no manual, no warning, no warranty

It’s worth summarizing what Hidden Desire actually publishes about this product, since the list is short. The manufacturer states: product name, article number 16881-BLACK, barcode 8713221835727, the product type Anal Gear, total length 45 centimeters, the material is smooth PVC, that the base is wide, the color is black, and the recommended retail price is 35,99 euro. The brand owner’s catalog adds insertion diameter 3,5 centimeters, weight 0,61 kilo, the packaging type is polybag, and the country of origin is China.

What the manufacturer does not publish is at least equally informative: no insertable length, no measurement of the baseboard, no shore hardness, no phthalate declaration, no care instructions, no lubricant recommendation, no warning text, no manual, and no warranty period. The user manual page on hiddendesire.eu covers seven product categories, and this one isn’t among them.

A detail in the brand owner’s catalog entry is worth mentioning for completeness: according to SCALA, the item may not be sold via Amazon, eBay, or other marketplaces. It doesn’t affect you as a buyer at the Swedish shops, but it explains why the product doesn’t show up in the usual price comparison services and why the number of sources to compare is so limited.

Hidden Desire Extreme XXL Anal Serpent compared with the alternatives

Three comparisons are relevant: against the nearly identical sister model, against the shorter variant of the same product, and against a competitor that provides more data than Hidden Desire does. All the measurements below come from the respective manufacturers’ own specifications, and all Swedish prices come from the shops’ product feeds on 29 July 2026.

Against Hidden Desire Extreme Anal Snake 45 cm — a half centimeter apart

Extreme Anal Snake 45 cm has model number 16879 and EAN 8713221835703. It is exactly the same length—45 centimeters—but the insertable diameter is 3 centimeters versus Serpent’s 3.5. The weight is 0.54 kilograms versus 0.61, and the list price is the same: 35.99 euros. Both are PVC, both have a wide base, and both lack a manual and a phthalate declaration.

The difference of half a centimeter in diameter is bigger than it sounds. The cross-sectional area is about 36 percent smaller on the Snake, and on a product that’s supposed to pass through a tight passage, that’s the figure that matters. So if you’re unsure whether 3.5 centimeters will work, Snake is the more cautious choice—and it doesn’t cost more. The cheapest Swedish shop lists Anal Snake 45 cm for 212 SEK, just like Serpent.

On the other hand: if you take into account that the spiral rib on Serpent sits on a shaft that’s half a centimeter thicker, the pattern will also be more pronounced. If you want the texture rather than the smallest possible range, Serpent is the model. It’s a choice between narrower and clearer—not between worse and better—and it’s well worth checking the EAN number before ordering, since the shops list both under almost the same heading.

Against Extreme Anal Serpent 35 cm — ten centimeters shorter, six euros cheaper

Extreme Anal Serpent 35 cm has model number 16880 and EAN 8713221835710. It has the same diameter—3.5 centimeters—same material and same shape—but the total length is 35 centimeters, the weight is 0.49 kilograms, and the list price is 29.99 euros instead of 35.99. On Swedish pages, we’ve seen it from 268.49 SEK—so actually more expensive than the 45-centimeter variant at the cheapest shop.

That makes the choice between them unusually easy in Sweden: the 45-centimeter version is cheaper at several shops even though it is 10 centimeters longer and costs 6 euros more in the suggested retail price. If you’re unsure how much length you want, there’s no price argument for choosing the shorter one. There is, however, a practical argument—an 35-centimeter-long product is easier to store, easier to handle, and takes up less space in a cabinet.

What’s right depends entirely on what you want to use the depth for. If you already have an anal toy in the shorter category, the whole point of this product is the extra 10 centimeters. If you don’t, the short version is a more reasonable starting point—even if you have to pay a little more for it in Sweden.

Mot XR Brands Hosed 18 Inch Swirl Thin Anal Snake — same idea, better documented

XR Brands sells under the Hosed brand a model that is strikingly similar: Hosed 18 Inch Swirl Thin Anal Snake, article number AF531. It is 19 inches total (48.3 centimeters), with 18 inches (45.7 centimeters) listed as insertable, and the diameter is 1 inch, i.e. 2.5 centimeters. The material is explicitly stated as phthalate-free PVC, the base is a suction cup that adheres to most flat surfaces, and the product is stated to work with both silicone- and water-based lubricants. The suggested retail price is 58.12 dollars.

The difference in the data is the whole point of the comparison. XR Brands publishes overall length and insertable length separately, a phthalate declaration, and an explicit lubricant usage statement. Hidden Desire publishes neither. Purely on specifications, the American product is better documented, and it is also one centimeter narrower, making it more accessible.

What Hidden Desire has going for it is price and availability. The suggested retail price of 35.99 euros versus 58.12 dollars is, in itself, a difference, and eight Swedish shops sell Serpent with Swedish shipping and Swedish right of withdrawal, while the XR Brands product must be ordered via specialized retailers. If you want a half-centimeter thicker shaft, a more pronounced spiral pattern, and a price from 212 SEK, then Hidden Desire is the choice. If you want a manufacturer that prints what the material contains, then this isn’t it.

Price range: 212 to 399 SEK at eight shops

Eight Swedish shops sell the item with EAN 8713221835727. Cheapest is Joyland at 212 SEK; most expensive are Lekosmek and Taboo at 399 SEK each. That’s a difference of 187 SEK or 88 percent for exactly the same article number, the same color, and the same polybag.

Seven out of eight shops had the product in stock at the price check. The only one missing was Sexonic at 322.21 SEK, so not the cheapest—which is unusual and means that, for once, the stock situation doesn’t affect the price you can actually buy at.

Shipping deserves its own line, because it changes the ranking in this price range. The retailers’ product flows show shipping of 98 SEK at Sexonic, 69 SEK at Joyland, 29 SEK at Blush Me and SexleksakerOutlet, and 0 SEK at Vuxenkul. Calculated with shipping included, Joyland lands at 281 SEK, Blush Me and SexleksakerOutlet at 278, and Vuxenkul at 279—so practically the same. Joyland’s 212 SEK is the cheapest on the shelf, but not necessarily the cheapest at checkout for a single item. Vuxen offers free shipping from 799 SEK and Lekosmek from 699 SEK—limits that a single item in this price range does not reach.

A note about the durability of the price data belongs here. The prices in the table above come from the retailers’ own product flows and are updated when the flows are updated. Individual stores adjust campaign prices more often than they update the flow, and in our review of the product pages, Joyland’s page showed a different price than the store’s own flow indicated. Always check the final price in the cart before confirming the purchase.

Who is Hidden Desire Extreme XXL Anal Serpent for—and who isn’t?

It’s for you if you’re already used to anal penetration deep inside and you want length rather than girth. With a 3.5-centimeter diameter, the product is narrower than most anal plugs in the XXL class—what makes it extreme is the 45 centimeters, not the thickness. It’s for you who want a clearly visible spiral pattern all the way through, for you who want to be able to use silicone-based lubricant without worrying about the material, and for you who want to enter this product category for about two hundred kronor.

It’s not for you if you’re buying your first anal toy. There is no waist in the shaft that marks a depth, no manual, no warning text, and no recommended usage depth from the manufacturer—so all responsibility for how far the product goes in lies with the user, and that’s a bad starting point without previous experience.

It’s also not for you if you require a materials declaration. The manufacturer writes PVC and nothing more, and the claims about phthalate-free and body-safety that appear in Swedish store texts are the retailers’ own. If you want a manufacturer that commits to phthalate-free in its own specification, you’ll find it in this category—but not Hidden Desire.

And it’s not for you if you want a product that lasts for years. Softened PVC is a consumable that changes on the surface over time, and unlike silicone, it can’t be boiled. Expect the product to need to be replaced when the surface starts to feel sticky, and count that cost as part of the price.

Warranty, complaints, and right of withdrawal

Hidden Desire leaves no product warranty and no warranty period. The manufacturer’s terms and conditions contain no warranty section whatsoever. What it says there instead is a set of deadlines: visible defects must be reported in writing or by phone no later than 48 hours after delivery, hidden defects must be reported within two months from when they were discovered, and if a complaint is approved, the manufacturer’s responsibility is limited to replacing the item.

The terms also provide a 30-day right of withdrawal for purchases made directly from the manufacturer, but with the express exception that products with a broken hygiene seal cannot be returned. Note that those terms apply to purchases in Hidden Desire’s own web shop. If you buy from any of the eight Swedish shops listed above, it is the shop’s terms and Swedish law that apply.

And there it looks better than the manufacturer’s terms suggest. Under the Swedish Consumer Sales Act (konsumentköplagen), you have three years’ right to complain about defects in the goods, regardless of what the manufacturer promises or chooses not to promise. The manufacturer’s 48-hour deadline does not apply against a Swedish shop. For distance sales, there is also a right of withdrawal for fourteen days under the Act on distance contracts and contracts outside business premises (lagen om distansavtal och avtal utanför affärslokaler).

A reservation that is especially relevant for this particular category of goods: the right of withdrawal is in practice limited for hygiene products that have been removed from a sealed package. The manufacturer’s packaging type is stated as a polybag, i.e. a plastic bag rather than a cardboard box, and that bag functions as a hygiene seal. The right to complain about defects, however, always applies. If you have questions about what applies in your case, the Swedish Consumer Agency (Konsumentverket) guides you via Hallå konsument.

Frequently asked questions about Hidden Desire Extreme XXL Anal Serpent 45 cm

How thick is the Hidden Desire Extreme XXL Anal Serpent really?
The manufacturer states an insertable diameter of 3.5 centimeters, and the figure is shown in two independent places: in the catalog entry for article 16881 of the brand owner SCALA 2.0 BV, and also shown directly in the manufacturer’s own measurement diagram 16881_BLACK_01. Three Swedish stores list something else—Vuxen och Blush Me write a maximum diameter of 3 centimeters and Joyland writes 4 centimeters—while Vuxenkul, Lekosmek, and Taboo stick to the manufacturer’s 3.5. Use 3.5 centimeters. The diameter is also constant from just below the tip to the neck, so it’s not a maximum value that only applies at a single point.
How much of the 45 centimeters can actually be inserted?
The manufacturer publishes only the total length of 45 centimeters and does not state an insertable length. The only source that provides a number for that is the retailer Joyland, which states 40 centimeters—meaning five centimeters less than the total length, roughly corresponding to the neck and the base plate. That’s a store claim and should be read as an estimate. For comparison, XR Brands lists both measurements separately for its corresponding model: 19 inches total and 18 inches insertable.
What’s the difference between Extreme Anal Serpent and Extreme Anal Snake?
A half centimeter in diameter, not the length. Both are 45 centimeters long and cost 35.99 euro in the list price. Anal Serpent has model number 16881, EAN 8713221835727, an insertable diameter of 3.5 centimeters, and weighs 0.61 kilo. Anal Snake has model number 16879, EAN 8713221835703, an insertable diameter of 3 centimeters, and weighs 0.54 kilo. The difference in cross-sectional area is about 36 percent, which is noticeable more than the names suggest. Check the EAN number before buying, because Swedish stores list both under almost identical headings and the cheapest store charges 212 SEK for both.
What material is it made of, and is it phthalate-free?
The material is PVC. The manufacturer writes “smooth PVC,” and the brand owner’s catalog lists PVC without any specification. Hidden Desire publishes no phthalate declaration for the product, either on the product page or in the catalog. The wording “Phthalate-free PVC” comes from Blush Me, and “body-safe PVC” from Lekosmek and Taboo—those are the stores’ own claims with no stated source. The Swedish Chemicals Agency describes phthalates as substances that can affect the hormone system, and soft PVC against the mucous membrane is exactly the kind of use where the question is relevant. If you want a manufacturer that itself makes a phthalate-free commitment, XR Brands does so in its specification for a corresponding model.
Which lubricant works with Hidden Desire Extreme XXL Anal Serpent?
Both water-based and silicone-based. The manufacturer gives no recommendation at all, because there is no manual for this product type, but PVC does not have silicone’s weakness—silicone-based lubricant does not break down PVC in the way it breaks down silicone sex toys. XR Brands explicitly states that its corresponding PVC model is compatible. On a 45-centimeter-long product, that is a real advantage, because silicone-based lubricant stays smooth for considerably longer than water-based lubricant. Joyland recommends water-based, which also works but needs to be reapplied more often. Oil-based products are a bad choice regardless of material.
Is the product waterproof—and what does the store’s IPX5 claim mean?
The product can be rinsed off in its entirety and used in the shower or bathtub, because it is a fully molded piece of plastic without electronics. The enclosure class “IPx5” that one of the stores lists, however, has no equivalent from the manufacturer and is also meaningless for this product type: IP classes according to IEC 60529 describe how well a housing protects electrical equipment against water, and here there is neither a housing nor electronics. Treat the number as the store’s own entry in a field that doesn’t belong on the product.
How do you clean and store a PVC product of this type?
Rinse off the entire product in lukewarm water with unperfumed soap or a cleaner intended for intimate products directly after use, and be especially careful in the spiral groove and in the transition between the shaft and the base plate. Let it air-dry completely before putting the product away—the spiral groove means it takes longer to dry than a smooth product. Never boil PVC and never put it in the dishwasher. Store it dry, cool, dark, and separately from other soft-plastic products, because plasticizers migrate between materials and two PVC toys that are kept pressed against each other can fuse together at the contact surface over time.
What warranty applies, and what happens if the product breaks?
Hidden Desire provides no product warranty. The manufacturer’s terms of sale contain no warranty section and no warranty period—only deadlines: visible defects must be reported within 48 hours after delivery, hidden defects within two months from discovery, and the responsibility in an approved complaint is limited to replacement of the item. Those terms apply to purchases made directly from the manufacturer. If you buy from a Swedish store instead, Swedish law applies, and there you have a three-year right to complain for defects in the item under konsumentköplagen and a 14-day right of withdrawal for distance purchases. In practice, the right of withdrawal is limited when the hygiene seal has been broken, and the manufacturer lists a polybag as the type of packaging—the bag is the seal.

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.
