Hidden Desire Extreme XL Dong Xtra Thick 28 cm: review

Extreme XL Dong Xtra Thick 28 cm at a glance — this is what you get

Hidden Desire Extreme XL Dong Xtra Thick is a massive, opaque black dildo without a motor, battery, or electronics. The manufacturer makes it in its range under the item number 16889-BLACK and classifies it as Anal Gear, meaning anal equipment, within the Extreme series. The material is stated as smooth PVC, and the base is described as wide, for safety and comfort. The recommended retail price in the manufacturer’s own store is 77,99 euro.

Three numbers define the product, and all three come from the manufacturer’s own measurement guide: the total length is 28 centimeters, the maximum diameter is 8 centimeters, and the weight is 2 kilos. These are the only measurements Hidden Desire publishes. In Sweden, the item is sold by five stores at prices between 395 and 795 SEK, and four of them had it in stock at the price check on 12 September 2026.

This review is exclusively about the black variant with EAN 8713221835802. The number is verified in three ways: it is present in the variant data on the manufacturer’s product page, Vuxen uses it directly as its own item number, and Sexonic lists it as EAN13 on its product page. The model only exists in black — Hidden Desire does not have a color variant with its own item number in this size.

What “Xtra Thick” means in numbers

The name does something unusual: it actually describes the product. In Hidden Desire’s Extreme Dong series, it’s the length that varies the most between models, while the diameter is usually around 5.5 to 7 centimeters. The two models that use the add-on Xtra Thick are the only ones with Ø 8 centimeters, and this one is the shorter of the two.

What can be established is that the diameter, not the length, is the product’s real feature. Eight centimeters in diameter corresponds to about the thickness of a soda can. Twenty-eight centimeters overall length is modest in this context—the same series includes models of 32, 33, 38, 43, and 52 centimeters. The price list shows the same thing: this model costs 77.99 euro from the manufacturer, while the five-centimeter longer XXL model at 33 centimeters costs 68.99 euro and the 32-centimeter-long XXL model costs 62.99 euro. You pay for the circumference, not the length.

The shape is realistic rather than abstract. The manufacturer’s product images show a curved, veined shaft form with a marked head, a scrotum that forms a wide base, and a separate round suction cup underneath it. Joyland describes the surface as veined and the hardness as medium; Vuxen describes the texture as realistic. None of this information comes from the manufacturer, which neither publishes hardness nor a surface description.

XL, XXL, or XXXL — which Extreme Dong is which?

Hidden Desires naming is easy to misunderstand, since the letters do not follow the length in a predictable way. This is what the models that are closest look like, according to the manufacturer’s own product pages and measurement images:

• Extreme Dong Xtra Thick XL 28 cm — item 16889, the model this text is about. 28 cm, Ø 8 cm, 2 kg, 77,99 euro.
• Extreme Dong Xtra Thick XXL 33 cm — item 16891. 33 cm, Ø 8 cm, 1,7 kg, 68,99 euro. Same maximum diameter, but five centimeters longer—and yet lighter and cheaper.
• Extreme Dong XXL 32 cm — item 16890. 32 cm, Ø 5,5 cm on the shaft and Ø 7 cm at the bottom, 1,5 kg, 62,99 euro. A slimmer model in the same length category.

The series continues upward with XXXL at 38 and 43 centimeters and XXXXL at 52 centimeters, at 74,99, 98,99, and 128,99 euro respectively. The point of the setup is that the letter designation says something about the length but nothing about the circumference, and that it’s the circumference that determines whether a product in this class is usable for you. If you want the maximum circumference, XL 28 cm and XXL 33 cm are the only two options within the brand.

Material and build quality: solid PVC without electronics

The material is the single most important characteristic of an insertable product, because it determines whether the product can be kept clean over time. Hidden Desire states one material for the entire product: smooth PVC. Intimico, which sells the same item in English, describes it as “smooth, high-quality PVC plastic”. All five Swedish stores also list PVC, which means there is no contradictory information on that point at all.

What PVC means in practice — and what it does not mean

PVC in this product category is plasticized polyvinyl chloride. Unlike silicone, which is soft thanks to its own polymer structure, PVC becomes soft by adding plasticizers. This is the fundamental difference between the materials, and it has two practical consequences.

The first is about the surface. A plasticized PVC surface is not as tight as a silicone surface. In this category, plasticized PVC is therefore treated as a material that can be cleaned but not completely disinfected, while medical-grade silicone, tempered glass, and polished steel are non-porous alternatives. That means, in practice, that a PVC dildo should be seen as a consumable with a limited lifespan rather than as a product you keep for ten years. It should also never be shared between people without a condom.

The second is about what the plasticizers are. Blush Me and SexleksakerOutlet both state “phthalate-free PVC” in their specification tables. The manufacturer itself makes no such commitment—Hidden Desire only writes “smooth PVC” and does not publish a material declaration. That is an important difference. A shop claim about phthalate-free is not the same as a declaration from the person who manufactures the product, and it can’t be checked against any document.

A small structural advantage is still worth mentioning. The product is molded in one piece, without openings, seams between different materials, or electronics. There is therefore no joint where dirt can collect, no button through which water can get in, and no battery compartment. In that respect, a solid PVC product is easier to take care of than a vibrator with multiple materials and a casing.

Phthalates, plasticizers, and what supervision actually found

Phthalates are a group of plasticizers used to make plastic—especially plasticized PVC—flexible. The Swedish Chemicals Agency describes them as substances that can affect the endocrine system and make reproduction more difficult, and several of them are therefore restricted or banned within the EU in a large number of product groups.

Sex toys are a special case. The Swedish Chemicals Agency finds that there is no specific chemical legislation for the product group. In an oversight project, the authority inspected 16 companies and checked 44 sex toys, mainly products in the lower price segment made of soft PVC plastic—exactly the category this product belongs to.

What this means for a buying decision is not that the product is dangerous. It means that the claim “phthalate-free” here lacks a source that can be verified, and that anyone who wants a material declaration to rely on should choose a brand that publishes one. The difference is clear when you compare with silicone products in the same price range, where the material information itself rules out phthalate plasticizers because silicone doesn’t need any.

Dimensions and weight: 28 cm, Ø 8 cm—and two kilo

The manufacturer’s size diagram specifies three values: 28 centimeters in total length, Ø 8 centimeters as the maximum diameter, and 2 kilograms in weight. That a manufacturer in this price segment publishes a weight at all is unusual, and it’s the piece of information that says the most about how the product actually works.

Two kilograms is a lot. The comparison within its own range makes it clear: the five centimeters longer XXL model at 33 centimeters, with the same maximum diameter Ø 8 centimeters, weighs 1.7 kilograms, and the 32-centimeter-long XXL model weighs 1.5 kilograms. So the shortest of the three is the heaviest, which can only be explained by the shape. Since the XXL models narrow toward the top, the 28-centimeter model keeps its thickness through almost the entire shaft and also has a massive base. Denser material over a shorter length.

In practice, this means the product isn’t one you’d hold in your hand for any longer period of time. Two kilograms in an outstretched arm becomes heavy fast, and that’s also why the suction cup is more than just an accessory on this particular model — it’s the primary form of use, not an alternative.

The manufacturer does not publish how much of the 28 centimeters is insertable. Joyland is the only one of the five stores that states an insertion length of 22 centimeters. The six-centimeter difference between total length and insertable length consists of the base and the suction cup. Since the information comes from a single store and not from the manufacturer, it should be read as a reasonable estimate rather than an exact measured value. The circumference is not published at all, either by the manufacturer or by any store, and this also applies to the suction cup’s diameter and the base’s width.

Use: 22 cm insertable, suction cup, and no locking mechanism

The product has no controls, no positions, and no manual. The only thing that determines how it’s used is the shape, and the shape consists of three parts: a bent, ribbed shaft, a wide base shaped like a pouch, and a round suction cup under the base. The manufacturer describes the wide base as a safety and comfort feature, and that description is the only usage guidance Hidden Desire publishes at all.

The suction cup and the base — what the base actually does

A wide base has two separate functions, and they’re often lumped together. The first is safety: a base that’s wider than the shaft acts as a stop and prevents the product from sliding in completely during anal use. That function is the entire reason why anal products should have a flared base, and it’s fulfilled here with good margin — the base is the widest part of the entire product.

The second one is fixation. The suction cup sits centered under the base and, according to all the stores, should attach to smooth, flat surfaces for hands-free use. Vuxen lists “Suction cup” as the type of feature in its specification table, and Blush Me and SexleksakerOutlet both write “Equipped with suction cup.”

What can be established is that the two functions place different requirements. The stop function depends only on the width of the base, and it is independent of weight. The suction function, on the other hand, should hold against two kilograms, and that is a real load for a suction cup of this size. The manufacturer does not publish the suction cup’s diameter or any measurement of the weight it is designed for. Assume that vertical mounting on a wall or a tiled surface is significantly more demanding than horizontal mounting on the floor or in a bathtub, where the weight instead presses the product against the surface.

The circumference that nobody publishes

The diameter Ø 8 centimeters is the figure that determines whether the product is realistic to use, and it is given by all sources. The circumference is not given by anyone. It’s a shortcoming, because it’s the circumference that most people have a reference value for — most people who buy in this category know roughly what circumference they can usually manage, but few have a frame of reference for diameters.

What can be established is that a diameter of 8 centimeters is at the absolute top of what is sold as a dildo at all, and that the step up to get there from a typical realistic model is very large. Compare it with Lovetoy Dual-Layered Silicone Nature Cock 27.5 cm, which is almost exactly the same length but has a maximum diameter of 5.3 centimeters. Two products with the same length, where one is more than fifty percent thicker than the other.

Vuxen summarizes the target group in a single line: “For the experienced user”. It is the only source in the entire material that even considers suitability, and the wording should be taken seriously. This product isn’t an entry-level model, and it isn’t also a natural next step from an average dildo.

Vaginal or anal? The sources say different things.

There is a real discrepancy between the sources here, and it’s worth stating plainly. The manufacturer classifies the item as Anal Gear and describes the entire series as XXL Anal Gear. Blush Me writes that the product is “designed to provide intense anal stimulation”. Intimico describes it in English as an anal stimulator. Vuxen, however, explicitly lists “For both vaginal and anal use”.

The manufacturer’s classification weighs the most. The product is constructed and marketed as an anal product, and the wide base is designed for that use. That a store also states vaginal use isn’t wrong in itself — the shape doesn’t prevent it — but it’s a store claim that goes beyond what the manufacturer writes, and it should be read as the store’s own assessment.

Lubricant: the point where the shops contradict each other

Of everything that can be controlled regarding this product, the lubricant question is the only one where the sources directly contradict each other, and it’s also the question with the greatest practical importance.

Which lubricant works with PVC?

Blush Me and SexleksakerOutlet both state that the product is compatible with both water-based and silicone-based lubricants. Joyland, in its specification table, states “Rek. glidmedel: Vattenbaserat,” and it also explicitly writes in the product text that you should make sure to use only water-based lubricant, since silicone-based lubricant can ruin the material. Hidden Desire publishes no lubricant recommendation at all—either on the product page or in any manual, because there is no manual for the Extreme series’ non-electrical products.

Without a statement from the manufacturer, there’s only one rational choice: follow the most cautious information. Water-based lubricant works on all materials in the category and can never damage a surface. Silicone-based lubricant is the type that’s known to break down silicone products, and when two out of four sources say it’s fine and one says it can ruin the material, the risk is asymmetric: if you choose wrong, you lose the product; if you choose water-based, you lose nothing except that you need to reapply more often.

Oil-based products like coconut oil don’t belong here at all. They leave a film that’s hard to remove on a porous surface, and with a product of this size, the surface that needs cleaning is very large.

Cleaning, storage, and durability

Joyland is the only source that publishes care instructions for the item. The shop specifies toy cleaning to clean the dildo, rinsing with warm water, thorough drying before storage, and storing the product separately from other toys in a cool, dry place.

The advice about separate storage isn’t a formality. Softened plastics can react with each other over time when they come into direct contact, which in practice shows up as sticky surfaces or discolorations where two products have been pressed against each other in a drawer. Considering that this product measures 28 centimeters and weighs two kilos, having its own bag or its own box is also the only practical solution.

The manufacturer publishes no temperature limit, no disinfection instructions, and no information about whether the product can be boiled. Since the material is softened PVC and not silicone, you should assume that it can’t. Boiling and the dishwasher are therefore out of the question, and this applies regardless of the fact that the product lacks electronics.

Documentation: what Hidden Desire publishes and what it doesn’t

A review based on published information must also report what is not published, because the absence of information is a characteristic of the product in the same way that measurements are.

Is there any manual for the Extreme series?

No. Hidden Desire has its own page for user manuals, and that’s where the documents for vibrating anal toys, Bangers masturbators, cock cages, sex swings, sex machines, electrical products, and dolls are located. Non-electrical dongs in the Extreme series are not included. That means there is no manufacturer guidance on cleaning, lubricants, temperature, or use for this specific item — and that’s the whole explanation for why stores can write different things without any of them being wrong in a formal sense.

What Hidden Desire actually publishes, however, is better than average in its price range: its own dimension chart with three values, a clear item number, a barcode that can be matched to the stores’ listings, and a list price. Many brands in the same segment don’t even publish a complete product page.

Warranty, hygiene seal, and the 48-hour rule

The manufacturer’s terms of purchase contain no product warranty and no warranty period. What is stated is the terms for buying in Hidden Desire’s own store: a 30-day right of withdrawal without stating a reason, that products with a broken hygiene seal cannot be returned, that visible defects must be reported within 48 hours from delivery, and that hidden defects must be reported within two months from discovery. The company behind the brand is listed as HIDDENDESIRE in Wijchen, the Netherlands, with trade register number 69251665.

Those terms apply to purchases made directly from the manufacturer. If you shop at any of the five Swedish stores, it’s the store’s terms and Swedish consumer law that apply — and as you can see further down, that legislation gives you more than the manufacturer’s terms do.

Extreme XL Dong Xtra Thick compared with the alternatives

Four comparisons are relevant: two against the manufacturer’s own sister models and two against products sold in the same Swedish store in the same size class. The sister models’ measurements come from Hidden Desire’s own dimension charts. The measurements for the other two come from Blush Mes specification tables, and are therefore store information, as are all the Swedish prices.

Extreme Dong Xtra Thick XXL 33 cm compared with the alternatives

The sister model 16891 is the only other product in the series with a Ø of 8 centimeters. It is 33 centimeters long versus 28, weighs 1.7 kilograms versus 2, and costs 68.99 euro versus 77.99 from the manufacturer. Five centimeters more product for nine euros less.

The difference lies in how the product is distributed in shape. The dimension images show that the 33-centimeter model reaches its maximum diameter along a marked, dome-shaped rim and then tapers toward the top, while the 28-centimeter model keeps a more even thickness over most of the shaft. In practice, that means the longer model gives you more length but a shorter section with full circumference, and the shorter model does the opposite. Which one is the right one depends entirely on whether you’re looking for depth or girth.

In Sweden, the XXL model is sold in the same store as this article, where it’s listed as Extreme Dong Extra Thick XXL 32.5 cm for 395 SEK — that is, the same price as the shorter model’s campaign price. Note that the store lists 32.5 centimeters, while the manufacturer lists 33. A half-centimeter discrepancy is insignificant in practice, but it’s an example of how store data drifts away from the manufacturer’s information, and when that happens, it’s the manufacturer’s details that apply.

Against Extreme Dong XXL 32 cm — narrower shaft, 15 euros cheaper

Article 16890 is the series’ slimmer alternative in the same length class: 32 centimeters long, Ø 5.5 centimeters on the shaft, and Ø 7 centimeters at the bottom, 1.5 kilograms, 62.99 euros. So it’s 15 euros cheaper than the 28-centimeter model and half a kilogram lighter.

This comparison is the most useful in the entire text, because it isolates exactly what the money goes to. You get four centimeters more length and pay 15 euros less — but you give up that centimeter in the maximum diameter that separates Ø 7 from Ø 8, and you give up the even thickness. In terms of circumference, that centimeter corresponds to a difference of a little over three centimeters all the way around. If you’re unsure whether Ø 8 centimeters is realistic for you, then the XXL model at 32 centimeters is obviously the more sensible step to take first.

Against Blush Dr. Skin Dr. Chubbs 25 cm — same price, smaller dimensions

Blush Dr. Skin Dr. Chubbs Vanilla is sold in the same store for 395 SEK, meaning it’s exactly the same price as this article has at its lowest. The store’s specification table lists total length as 25.00 centimeters, insertion length as 18.00 centimeters, maximum diameter as 7.60 centimeters, and the material “skin-friendly PVC” in the color nude.

It’s the closest direct competitor in both price and material class. The differences are small but consistent: the Hidden Desire model is three centimeters longer, four millimeters thicker, and according to Joyland’s listing, has four centimeters more insertion length. Dr. Chubbs, on the other hand, publishes an insertion length in the store’s standard specification table instead of as a single store listing, and it comes in a skin tone for those who don’t want black. In pure size per krona, Hidden Desire wins, but the margin is smaller than the name difference suggests.

Against Lovetoy Nature Cock 27.5 cm — silicone instead of PVC

Lovetoy Dual-Layered Silicone Nature Cock is almost exactly the same length: 27.50 centimeters versus 28. The insertable length is specified as 20.00 centimeters and the maximum diameter as 5.30 centimeters. The material is listed as high-quality silicone, and the price is 495 SEK in the same store.

This comparison really puts the material question to the test. For one hundred kronor more, you get the same length in silicone instead of PVC — meaning a non-porous material that can be cleaned completely and that doesn’t require plasticizers. What you give up is the girth, and you give up a lot of it: 5.3 centimeters versus 8 is a difference of 2.7 centimeters in diameter, which is far more than what any other comparison in this text is about.

The conclusion is simple and uncomfortable. If you want a material that lasts, there’s nothing to choose from in this diameter class — silicone products with a Ø of 8 centimeters in the price range under one thousand kronor are, in practice, nonexistent. Extreme girth and non-porous material are two properties you can’t buy at the same time for 395 SEK. Someone who prioritizes the material should buy the Lovetoy model and accept a narrower measurement; someone who prioritizes the girth should buy this one and treat it as a disposable item.

Price range: 395 to 795 SEK at five stores

Five Swedish stores sell the item with EAN 8713221835802. The cheapest are Blush Me and SexleksakerOutlet at 395 SEK each, then Joyland at 549 SEK, Sexonic at 694 SEK, and Vuxen at 795 SEK. That’s a difference of 400 SEK, or just over 101 percent, between the cheapest and the most expensive store for exactly the same item number, the same color, and the same packaging.

The stock situation is unusually good in this category. Fyra av de fem butikerna hade produkten i lager vid priskontrollen, and both of the cheapest were among them. The only one that was sold out in the product flow was Sexonic, which is also the second most expensive. That means the 400 SEK price spread is fully relevant — you can actually buy at the lowest price, which isn’t always the case.

It’s also worth noting what 795 SEK is. Blush Me lists 795 SEK as the regular price and 395 SEK as the promotional price, meaning exactly the price that Vuxen charges. The price picture therefore doesn’t reflect different purchasing costs, but rather that two stores run a promotion while one leaves it at the list price. The manufacturer’s own recommended retail price in its own store is 77.99 euro.

The prices in the table above are updated when the stores’ product flows are updated, but always check the final price at checkout. For a product that weighs two kilograms, shipping cost is also a real part of the total price — check the free-shipping threshold before you compare, because the difference between the two stores of 395 SEK very well could be determined there.

Who is it suitable for — and who isn’t it for?

It fits you specifically if you’re looking for a circumference and already know that Ø 8 centimeters is realistic for you. It fits you if you want a hands-free product with a wide base and a suction cup rather than something to hold in your hand. It fits you if you want the maximum size for under four hundred kronor and who understands that the material is softened PVC and not silicone. And it fits the person who appreciates that the manufacturer actually publishes three measurements in its own measurement diagram instead of only writing “XL”.

It doesn’t fit you if you’re a beginner. The manufacturer’s own wording “For the experienced user” is the only suitability assessment found in the material, and it should be taken at face value. It doesn’t fit you if you want a non-porous material that can be disinfected—there, silicone is the only answer, and in this diameter class silicone is practically not available to get. It doesn’t fit you if you want a documented product: there is no manual, no warranty period, no circumference, no hardness specification from the manufacturer, and no clear lubricant recommendation.

And it doesn’t fit you if you want something easy to handle. Two kilos is a real characteristic, not just a detail in a specification. It affects how the product can be used, where it can be mounted, how it should be stored, and what shipping costs. If anything in this review is going to determine the purchase, it’s that number together with the diameter—not the length, and not the price.

Warranty, claims, and right of withdrawal

Hidden Desire provides no product warranty. The manufacturer’s terms of purchase include neither a warranty period nor a commitment to compensation in case of defects, and there is no warranty registration you can make. What the terms say is that visible defects must be reported within 48 hours after delivery, and hidden defects within two months after they are discovered, and that products with a broken hygiene seal cannot be returned. Those terms apply to purchases in the manufacturer’s own store.

If you shop in Sweden, the situation is different—and better. According to konsumentköplagen, you have three years of right to complain about defects in the goods, regardless of what the manufacturer does or does not promise. That right cannot be waived, and it applies to all five shops in the table above. For distance purchases, you also have a right of withdrawal for fourteen days under the lagen om distansavtal och avtal utanför affärslokaler.

Be aware that in practice the right of withdrawal is limited for hygiene products that have been removed from a sealed package — Konsumentverket provides guidance on exactly how the exception works. However, the right to make a complaint for defects always applies. On a product like this, this is relevant: a casting defect, a crack in the base, or a suction cup that comes loose from the material are manufacturing defects and are covered by the right to make a complaint, while wear on the surface after use does not. If you have questions about what applies in your case, Konsumentverket guides you via Hallå konsument.
