Review · Anal plug · Opening gaps in silicone
Hidden Desires opening 4-way plug reviewed against the manufacturer’s own specifications and price data from six Swedish stores. Total length 6 centimeters, unfolded diameter 7,5 centimeters, through channel on Ø 2,3 centimeters, and 100% silicone — but neither insertion diameter, insertable length, nor warranty period is published by the manufacturer.
A cheap and structurally pared-down opening plug: four silicone flaps that fold out to Ø 7,5 centimeters, a through channel on Ø 2,3 centimeters, and nothing that can break, because the expansion is passive. The manufacturer lists dimensions, weight, packaging, and country of origin. What pulls the rating down is the gaps: insertion diameter, insertable length, the material’s hardness, and the warranty period are not published by any source, making it difficult to assess the difficulty level in advance.
Extreme Spreader 4-Way Plug is an anal plug that is not built to fill out, but to open. It consists of four silicone flaps around a central core, and the design makes the flaps rest against the core during insertion and then fold out once the plug is in place. The manufacturer places it in its own product category Gapers – Open Plug, meaning opening plugs, and that label explains the product better than the word anal plug does.
The specification is short but concrete. The manufacturer lists the total length as 6 centimeters, the product size as 6 × 7.5 centimeters, the material as silicone, and the weight as 0.14 kilo per unit. The manufacturer’s own dimension graphic adds the diameter of the through-hole: 2.3 centimeters. There is no motor, no battery, and no electronics, which also means there is no IP rating to report. The packaging is a carton measuring 18.5 × 9.4 × 9.4 centimeters, and the country of origin is listed as China.
This review is about the black variant with EAN 8713221833143, the manufacturer’s article number 16803, and variant SKU 16803-BLACK. It’s straightforward in this case: the item is available in only one color, and the barcode in the manufacturer’s own product data matches the EAN number exactly in the Swedish shop feeds. Six Swedish shops sell the item for prices between 188 and 309 SEK, and four of them had it in stock at the price check.
A regular anal plug is solid and has a fixed cross-section. It stays in place because the shape is narrower at the neck than at the widest point, and the sensation it provides is a constant filling. A gaper — also called an open plug or tunnel plug — works the other way around. It’s hollow and designed to keep the tissue stretched without filling the middle. The manufacturer lists the diameter of the through-hole as 2.3 centimeters, and the manufacturer’s product photo seen from underneath shows that the channel runs straight through the entire product, from the base up through the tip.
The difference is fundamental and determines who the product is suited for. If you’re looking for weight and a filling sensation, you’ll get that better from a solid plug. If you’re looking for the feeling of being open, or if you want to add lubricant or something else through the channel while the plug is in place, you’ll only get that from a gaper. What makes this specific model unusual is that it combines both ideas: it’s both hollow and expanding. The manufacturer describes it as designed to glide in as softly as possible and then open and expand once it’s in place.
The name gives the impression of a mechanism, and it’s worth clarifying right away. There is no mechanism. The manufacturer states that the material is silicone and nothing else in the spec table, and it shows neither a valve, a pump, threads, nor a moving part. The expansion is passive and comes from the silicone’s own springiness: the flaps want to return to their extended rest position, and what they encounter in the extended position is the body.
The manufacturer’s own product photos clearly show the two positions. In the folded position, the four flaps rest against the conical central core and together form a tapering profile above the base—this is the shape that is inserted. In the extended position, the flaps stick out in four directions, and the total measurement across them is 7.5 centimeters according to the manufacturer’s size graphic.
What that means in practice is that you don’t control the expansion. You can’t choose for it to open halfway and stay there, unlike an inflatable plug where you control the final size with a pump bulb. Either it sits far enough inside for the flaps to unfold, or it doesn’t. That’s also the advantage: there’s nothing that can break, no valve that can get stuck, and nothing that can be inflated too much. The entire product is molded as one piece of silicone.
What can be said about the shape is that the outer edge of the flaps isn’t sharp. The manufacturer’s close-up view from above shows rounded, leaf-shaped flaps with a beveled edge and a clear longitudinal reinforcement in the middle of each flap. The reinforcement is what gives the flaps spring-like action in the first place—without it, they would just be pushed aside.
The measurements are the most important line in the specification for a product of this kind, and Hidden Desire is unusually clear on two out of three points. The manufacturer states the product dimensions—6 × 7.5 centimeters—and the total length of 6 centimeters in its spec table. The shops reproduce the same figures: Joyland lists a length of 6 centimeters and a width of 7.5 centimeters; Vuxen lists a total length of 6 centimeters and a maximum diameter of 7.5 centimeters; Blush Me and SexleksakerOutlet list a total length of 6 centimeters and a max diameter (open) of 7.5 centimeters. So there is full agreement between the manufacturer and all Swedish shops on the two main measurements—which is unusual enough to earn a line.
The manufacturer publishes its own dimension graphic in the product gallery, where three numbers are shown: the height 6 centimeters measured from the underside of the base to the top of the flaps, the unfolded width 7.5 centimeters measured across the flaps, and the through-hole diameter Ø 2.3 centimeters. The third number is not in the manufacturer’s spectabell, only in the graphic, and that explains why several stores list it even though it doesn’t appear in the technical fields. Blush Me, SexleksakerOutlet, and Vuxen all state 2.3 centimeters as the inner diameter, and they therefore match the manufacturer.
Then comes the flap, and it’s big. The manufacturer publishes no insertion diameter—meaning how wide the plug is in the folded-down position, when it’s inserted. This is the only figure that determines whether the product can be inserted at all, and it’s missing from the manufacturer and from all six Swedish stores. The same applies to the insertable length: 6 centimeters is the total length including the base, and how much of it actually goes in is not shown. For the sister models in the same series, Hidden Desire publishes both of these measurements—Extreme Inflatable Smooth Plug Starter is listed as an insertable length of 10.5–14.5 centimeters and an insertable diameter of 3–5.5 centimeters—so it’s not a general lack on the brand’s part, but a lack specific to this particular item.
What you can take from it is the following. The measurement 7.5 centimeters is the product’s largest measurement in the unfolded position and thus describes the final position, not the entry. The measurement 2.3 centimeters describes the hole, not the material around the hole. Nowhere is there a number that describes the cross-section the body meets at the moment of insertion, and that makes it difficult to judge the difficulty level in advance. The manufacturer’s picture of the folded-down position shows a profile that’s noticeably narrower than 7.5 centimeters, but a picture is not a measurement.
Weight is published, which is more than many manufacturers in the category do, but two of the manufacturer’s own fields say different things. The spectabellen on the product page lists weight per unit as 0.14 kilo. The article data behind the same page lists the variant’s weight as 0.135 kilo. The difference is 5 gram and has no practical significance, but it’s worth noting because it shows that the spectabellen’s figure is rounded. Count on about 135–140 gram of silicone.
Seen in terms of what 135 gram means in your hand: it’s a compact, heavy little thing for its size, which is to be expected since silicone is significantly denser than the air that an inflatable plug is filled with. For comparison, the manufacturer publishes no weight at all for Heavy Anal Stretcher Plug M in the same series, even though that model’s name is based on that very weight.
Anal products have a single absolute construction requirement, and it is that they must not be able to disappear in. The requirement is met by a base that is wider than the product’s narrowest part and that can’t be pulled in. The manufacturer states that the product has a wide base for safety and comfort, and Vuxen lists the base type as flared.
The manufacturer’s own product photos show what the base actually looks like, and it isn’t a flat plate. It’s designed like a bent, oblong bracket—wide across and bent upward at both ends, roughly like an anchor. The shape does two things. It rests against the body along a line rather than against a circle, which is more comfortable to sit or lie on than a round flange. And it gives you something to grip when removing it, which is a real thing on a product that’s only 6 centimeters long and therefore has no handle.
Running through the base is the oval hole of 2.3 centimeters. That means the base is a ring rather than a plate, and it’s a trade-off: a ring with a 2.3-centimeter opening has less contact area than a full sheet of the same outer dimensions. The manufacturer publishes no measurement for the base’s width or thickness—those would be the figures that would make it possible to assess the margin. What can be established from the manufacturer’s own image is that the base is clearly wider than the fin tabs’ attachment.
The material issue is the only characteristic of an intimate product that can’t be compensated for with experience or care. Here, the message is unambiguous on one level and blank on another. The manufacturer’s spectabell lists a single material: silicone. The product text specifies it as 100 percent pure silicone, and the manufacturer’s packaging image shows the labeling 100 % SOFT-SILICONE printed on the cardboard together with the series name EXTREME by Hidden Desire and the category ANAL GEAR.
Silicone is a pore-free material. A pore-free surface can be cleaned, because there are no microscopic cavities where residue can get left behind. That is the single most important property of a material that’s meant to lie against mucous tissue, and it weighs more heavily than almost every other item in a specification.
That the product is also molded in one single piece further reinforces the advantage. There’s no seam between two materials, no glued joint, and no assembled part where dirt can collect. That’s a concrete difference from inflatable plugs in the same series, where a sealed air chamber and a hose connection mean the inside can never be cleaned. Here, the entire inside is accessible, because the channel is open at both ends.
The manufacturer does not state the silicone’s Shore A hardness, which is the figure that would have said something about how rigid the flaps are and therefore how hard they press outward. Joyland states the hardness as “medium” and the surface as silky and smooth, but this is a store claim and a qualitative one at that. For a product whose entire function is based on the material’s springiness, it is the most missing piece of information after the insertion diameter.
Phthalates are a group of plasticizers used to make plastic—above all pliable PVC—flexible. 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. The category of intimate products is a recurring subject of oversight precisely because it contains pliable plastic against the skin.
It is important here to distinguish between what is actually stated and what is not. Hidden Desire does not publish any phthalate declaration, any BPA declaration, and any latex declaration for this article. What the manufacturer writes is the material: silicone, 100 percent pure silicone, 100 percent soft-silicone. The retailer Joyland, however, explicitly states “Phthalate-free: Yes” in its own specification table. This is a store claim and should be read as such.
Chemically speaking, the silicone specification is still better information than most of the material entries you encounter in this category. Silicone does not require phthalate plasticizers to become soft—the softness comes from the polymer’s own structure—and that is why someone buying a silicone product is buying something other than a product labeled “TPE” or “jelly rubber,” terms that say absolutely nothing about which plasticizers are included. Silicone also does not contain natural rubber latex, which is relevant for anyone who is latex-allergic and would otherwise have to avoid the entire category of inflatable plugs made of latex. But drawing that conclusion is the reader’s own reasoning about the material, not a commitment from Hidden Desire.
The manufacturer’s own description is brief and to the point: the plug is designed to glide in as softly as possible, and once it is seated deep in place, it opens up and expands. With the spreader in place, extra lubricants can be added through the hole, and the wide base is there for safety and comfort.
From the construction, it’s clear that the order matters. The flaps must pass completely past the sphincter muscle before they can unfold—this is the geometric requirement for them to have somewhere to fold out. With a total length of just 6 centimeters, of which part is the base, there isn’t much room for margin. If the plug sits too shallowly, the flaps will resist instead of opening, and if it’s positioned correctly, the base’s brace is what remains outside.
The cutout is the phase where an expanding plug differs from a regular one. The flaps are unfolded and must fold back together on the way out. This happens automatically because they are conical and taper toward the tip, but it assumes that you pull slowly and straight rather than quickly and at an angle. The manufacturer does not publish a user manual for the item and writes nothing about the cutout.
This is the point where the sources actually diverge, and the deviation is worth stating plainly. Four out of six shops list water-based lube: Joyland lists “Recommended lube: Water-based” in its specification table, Vuxen, SexleksakerOutlet, and Blush Me all explicitly state that water-based lube should be used, and the Swiss retailer Joujou does the same.
Vuxenkul claims the opposite, saying that both water-based and silicone-based lube work perfectly with the product. It’s a store claim that contradicts all the other sources, and it should not be followed. Silicone-based lube on a silicone product breaks down the surface over time and makes it porous, and a porous surface can no longer be cleaned properly—only thrown away. The fact that it says so on a single shop page doesn’t make it any less wrong. Use water-based lube.
An addition that is specific to this gaper in particular: since the channel is open, it’s possible to apply lube while the product is in place, which the manufacturer itself highlights as a feature. It’s a real practical advantage compared with a solid plug, where all the lube must be in place before.
The shop instructions are consistent: clean with toy cleaner before and after each use, or alternatively with warm water and mild soap. Joujou states antibacterial cleaning before and after each use. The manufacturer publishes no care instructions of its own for the item.
The construction makes cleaning easier than most in this category. The 2.3-centimeter channel goes straight through, which means the inside can be rinsed through instead of just wiped. The spaces between the four flaps are where residue can actually remain, and they’re accessible because the flaps can be bent apart by hand. Let the product air-dry completely before putting it away.
Vuxenkul also states that the silicone can be boiled for deep cleaning. It is a store claim that the manufacturer does not publish, and it should be treated as unconfirmed. Solid platinum silicone generally tolerates boiling, but without a material specification that distinguishes platinum-cured silicone from tin-cured silicone, it’s not possible to know what kind of silicone this product is molded in. Boiling water and soap are the instructions that are supported.
The manufacturer expressly mentions lubricant through the hole. Several of the Swedish stores go further and describe the channel as a portal for other toys — Blush Me and SexleksakerOutlet phrase it as the hollow with an open center making it possible to use the plug as a portal accessory for other toys, and Vuxen writes the same thing.
Here it’s worth being exact about the number. 2.3 centimeters is the diameter of the hole, not a recommendation. What goes through the channel therefore encounters a fixed opening that does not give way to the sides in the same way the body does, because the channel is surrounded by silicone material on all sides. The manufacturer publishes no information about what the channel is dimensioned for and no warning text for use. So what can be established is only the measurement — the rest is store copy.
Three things apply to all anal products and are worth repeating, because neither the manufacturer nor the stores publish any safety text for this item.
No, and there are two reasons that can both be derived from the specification. The first is the shape: a product that unfolds to 7.5 centimeters across is not an introductory product, and the manufacturer places it itself in a line marketed toward people looking for intensity and progression. The stores describe it consistently as intended for advanced users.
The second reason is precisely the lack of an insertion measurement. A beginner needs to know how wide something is before it goes in, and that figure isn’t available. An experienced user can judge it from the pictures and their own experience; an inexperienced user has nothing to go on. If you want to start somewhere within the same series, Extreme Inflatable Smooth Plug Starter is the logical choice, because it states an insertable diameter that starts at 3 centimeters and that you control upward yourself.
A cold review of a product lives or dies by what the manufacturer has actually written down. Here are the facts, split into two lists.
Published: article number 16803, variant-SKU 16803-BLACK, barcode 8713221833143, product dimensions 6 × 7.5 centimeters, total length 6 centimeters, hole diameter 2.3 centimeters (in the dimension graphic), material silicone, weight 0.14 and 0.135 kilograms respectively, packaging carton 18.5 × 9.4 × 9.4 centimeters, master carton of 100 pieces, the color black and country of origin China.
Not published: insertion diameter in folded position, insertable length, base width and thickness, silicone hardness in Shore A, phthalate, BPA and latex declaration, user manual, care instructions, maximum usage time, warranty period, recommended consumer price, and any EU declaration of conformity. It’s a long list, and it is in itself one of the most important results of this review.
Hidden Desire is not a standalone brand with its own consumer website. The name is a trade name owned by the Dutch wholesaler Scala 2.0 B.V. in Wijchen, together with, among others, ToyJoy, Taboom and Playhouse. It is also at SCALA that the article’s official product data is published, and that’s where the Extreme by Hidden Desire series was launched to the retailer channel as a range for anal use, performance-enhancing accessories, and fetish-inspired products. In the manufacturer’s own article data, Baco Industrial Co Ltd is also listed as the supplier behind the article.
That explains some of the documentation gaps. A wholesale-driven brand line doesn’t have its own customer support line and no consumer website to put manuals on, and the result is that the only complete specification ends up in a B2B flow aimed at stores. That the specification is nevertheless as detailed as it is—measurements, weight, packaging, country of origin—actually belongs among the better parts in this price range.
One thing to know when you compare stores. The same item appears under at least five different numbers in the Swedish retail channel, which makes it harder than necessary to know that you’re looking at the same thing. The manufacturer’s own number is 16803 with variant-SKU 16803-BLACK. Vuxenkul lists the manufacturer’s item number as SC4011-1. Joyland uses its own number 26619, the Vuxen combination 30337-8713221833143, and Sexonic the references 1808 and 20577, respectively. Blush Me and SexleksakerOutlet use the EAN number directly.
The only identifier that is common to all of them is EAN 8713221833143, and it matches the barcode in the manufacturer’s own item data. If you’re not sure whether two store pages show the same thing: compare EAN, not names. The item is sold under at least four different product names in Sweden — Extreme Spreader 4-Way Plug, Spreader 4-Way Plug, Hidden Desire Extreme: Spreader 4-Way Anal Gear Plug, and Hidden Desire Extreme Expanding Anal Spreader Plug.
We do not have price data from shops in your market yet.
The manufacturer states how wide the plug is when it is spread out, but never how wide it is as it goes in. That is the only measurement that determines whether it can be inserted.
Three comparisons are relevant: against the adjustable way to the same goal, against the simple way to the same goal, and against the same design idea in a completely different material. All the specifications below come from each item’s official product page from the manufacturer, and all prices come from the stores’ product feeds on July 29, 2026.
The sister model in the same series costs from 212 SEK, i.e., 7 SEK less than Spreader 4-Way at its lowest in stock. It solves the same basic problem — to enter narrow and then become wider — but with a completely different method. The manufacturer states an insertable diameter of 3–5.5 centimeters and an insertable length of 10.5–14.5 centimeters, and the expansion is done with a hand pump that you control yourself.
The differences that actually matter: the inflatable lists both the insertable diameter and the insertable length, which Spreader 4-Way does not, and it lets you stay where you want on the scale. Spreader 4-Way, on the other hand, has no valve that can malfunction, no sealed chamber that can’t be cleaned on the inside, and no hose sticking out outside. It’s also significantly shorter — 6 centimeters total versus a minimum of 10.5 centimeters insertable — and above all, it’s hollow, which the inflatable is not.
The conclusion is simple. If you want control over the final size and the stated insertion measurements, the inflatable is the better buy, and it costs less. If you want an open channel through the product, that function only exists on Spreader 4-Way — the inflatable is solid, and you can’t add a hole in an air chamber.
Heavy Anal Stretcher Plug M costs from 179 SEK and is the cheapest of the three comparisons. The manufacturer states a total length of 14 centimeters, an insertable length of 11.5 centimeters, and an insertable diameter of 5.5 centimeters, all in silicone. So here you get the complete set of measurements: total, insertable, and diameter.
At the same time, it’s a different kind of product. The 5.5-centimeter measurement is fixed—it’s just as wide on the way in as when it’s in place, which means that all the difficulty lies in the insertion. Spreader 4-Way shifts the difficulty to the other side: a narrow profile in, 7.5 centimeters across when it’s in place. The stretcher is also almost twice as long insertably, 11.5 compared to a total length of 6 centimeters, and it’s solid instead of hollow.
So for 40 SEK less, you get a product with fully stated measurements and a larger insertable measurement, but without expansion and without a channel. If what you’re after is expansion rather than filling, Spreader 4-Way is still the only one of the two that does that.
Mr. Steel Ass Blaster Medium is a tunnel plug of the same basic type—hollow, intended to stay open—but made of metal. The manufacturer states the material as aluminum, the product dimensions as 10.8 × 5.0 centimeters, the total length as 10.8 centimeters, the insertable length as 10 centimeters, and the insertable diameter as 5 centimeters. The price is 761 SEK, i.e., 542 SEK more than Spreader 4-Way.
The difference in material is crucial and goes both ways. Aluminum is hard and doesn’t give, which means that the insertion diameter of 5 centimeters is exactly what the body meets—no flexing, no tolerance. On the other hand, metal is as pore-free as silicone: it tolerates boiling without reservations, and it conducts heat and cold in a way that silicone doesn’t. Mr. Steel also publishes the full set of measurements, unlike Spreader 4-Way.
If you choose based on price and how soft something should be, Spreader 4-Way wins by a wide margin. If you choose based on stated measurements, durability, and cleanability, the metal wins—but it costs more than three and a half times as much.
Six Swedish stores sell the item with EAN 8713221833143, spread across seven listings. The cheapest is Vuxenkul at 188 SEK, and the most expensive is Vuxen at 309 SEK. That’s a 121 SEK difference, or 64 percent, for exactly the same item number, same color, and same packaging.
The inventory situation changes the picture. Vuxenkul, which had the lowest price, had the product sold out at the price check, and the same applied to both Sexonic listings at 241.63 SEK. Four stores had it in stock: Blush Me and SexleksakerOutlet at 219 SEK each, Joyland at 251 SEK, and Vuxen at 309 SEK. This means that the lowest available price level is 219 SEK, not 188, and that the range between the cheapest and the most expensive available is 90 SEK.
Shipping costs are worth considering in this price range, since they make up a large share of the product price. Blush Me and SexleksakerOutlet list 29 SEK in shipping in their feeds, Joyland 59 SEK, and Sexonic 98 SEK—plus the last store ships from Marbella in Spain, which is worth knowing for the delivery time. Sexonics 241.63 SEK plus 98 SEK shipping thus ends up above Vuxen’s 309 SEK, even though the item price looks lower in the table.
The price spread is not because any store sells another variant. The item is available only in one color from the manufacturer, and all seven listings have the same EAN. It’s therefore about the stores’ own margin setting for an item that has been in the range since 2025—and that’s exactly the kind of situation where a quick comparison is most worthwhile.
A note about the store data that’s worth printing out. Sexonic lists the same EAN twice, under two different reference numbers and two different product names: 1808 under the name "Hidden Desire Spreader 4-Way Plug Black" in the category Gapers – Öppna pluggen, and 20577 under the name "Hidden Desire – Extreme Expanding Anal Spreader Plug" in the category BDSM Analplugg. The price is identical on both, 241.63 SEK.
So it’s not two variants, but a duplicate in the store’s own range, and it shows up as two rows in the price table above because the store’s feed supplies it that way. It’s harmless but worth knowing: if you find the item under two names in the same store, it’s the same product, and you don’t need to wonder which one is the right one.
It’s for you if you already have experience with anal use and are specifically looking for the feeling of being spread out rather than filled. It’s for you if you want an open channel through the product—either to add lubricant during use or for what stores describe as a portal function. It’s for you if you want silicone throughout the entire product without seams, and you value that the whole inside can be rinsed through. And it’s for you if you want something short: 6 centimeters total is unusually little in this product type.
It doesn’t suit you if you’re a beginner, for the reasons above. It doesn’t suit you if you want to be able to control how much it opens—where the inflatable sister model is the right product. It doesn’t suit you if you require a complete set of measurements before purchasing, because neither the insertion diameter nor the insertable length is published by any source. And it doesn’t suit you if you want manufacturer documentation to lean on: there is no manual, no warranty commitment, and no phthalate- or latex declaration.
One more thing belongs in the decision. The price of 219 SEK makes this an inexpensive way to find out whether a gaper is something for you at all. In this category, there are products that cost three times as much for the same function in another material, and what distinguishes them is primarily durability and reporting—not what they do.
Hidden Desire does not publish a warranty period for this item. There is no warranty page, no warranty terms, and no commitment stated in the product data. This in itself isn’t unusual for a product without electronics, but it means that the only thing you have to go on is the statutory protection—and in return it’s stronger than most people think.
According to the Swedish Consumer Sales Act (konsumentköplagen), you have three years to complain about defects in the item, regardless of what the manufacturer undertakes to provide or fails to do. A defect that existed at delivery—a casting defect in the silicone, a crack in a flap, a defect in the base—is a defect you can complain to the store about for three years. The right to complain is directed at the store you bought from, not the manufacturer, which is practical here since the manufacturer has no consumer channel.
For distance purchases, you also have a right of withdrawal for fourteen days under the Law on distance contracts and contracts outside business premises. Be aware that, in practice, the right of withdrawal is limited for hygiene products that have been taken out of a sealed package—and this item is delivered in a cardboard box measuring 18.5 × 9.4 × 9.4 centimeters. So if you want to be able to withdraw from the purchase, the packaging must therefore be unopened. The right to complain about defects, however, always applies, whether the package is sealed or not. If you have questions about what applies in your case, Konsumentverket will guide you via Hallå konsument.
