Silexd Silex-D Dual Density Silicone Dildo 17.6 cm: review

Silexd’s smallest model compared with the manufacturer’s own specifications. Total length 17.6 cm, insertable 13.6 cm, diameter 3.5 cm, weight 251 grams, and a suction cup base of 6.7 cm — in platinum silicone over a Silexpan core.

My rating

The cheapest way to platinum silicone in this size. The dual-density construction gives a firm core and a soft surface in a non-porous material; the suction cup is wide relative to the product’s 251 g, and thermoreactivity is a real function rather than a marketing buzzword. What you pay for is transparency: the core’s composition isn’t published, no Shore hardness is stated, and the manufacturer offers no voluntary warranty at all. Since three of seven stores also list the wrong length, the EAN number is the only thing you can rely on when comparing prices.

  • Total length 17.6 cm, insertable 13.6 cm, diameter 3.5 cm
  • Weight 251 g — suction cup with a 6.7 cm base
  • Platinum silicone over the patented Silexpan core
  • Thermoreactive: softer when warm, harder when cold
  • No voluntary manufacturer warranty — only statutory liability for defects
  • No shop in our data sells this product in this market.

Silexd Silex-D Dual Density Silicone Dildo 17.6 cm at a glance

Silexd Silex-D Dual Density Silicone Dildo 17.6 cm is the smallest model with a shaft in Silexd’s series The Original, and the one the manufacturer itself calls Model 1 7". It’s a realistic dildo without a motor, without a battery, and without an app — the entire construction lies in the material and the shape. What sets it apart from a regular silicone dildo is that it’s built in two densities: a firm core of the patented material Silexpan, and on top of that a soft skin of platinum silicone.

The manufacturer’s specification looks like this: the total length is 17.6 centimeters, the insertable length is 13.6 centimeters, and the diameter is 3.5 centimeters. The weight is listed as 251 grams, and the base is a suction cup with a diameter of 6.7 centimeters. The material is described as SILEXPAN® in combination with platinum silicone, the construction as thermoreactive, and the surface as pore-free and phthalate-free. In the package, the product and an instruction sheet are included — nothing else.

This review is exclusively about the skin-colored variant with EAN 8433345220277, the manufacturer’s item number 220277 in the color Flesh. Silexd sells the same model in three additional colors with their own EAN numbers — Pink with 8433345220215, Black with 8433345220291, and Caramel with 8433345220260 — plus a separate Purple Edition. The measurements are identical, but the number is the only thing that safely differentiates them in the stores’ feeds, and as you will soon see, in this particular case the store product name is an unusually poor guide for finding the right item in store.

What dual density means, and why you can feel it

Dual density — double density — means that the product consists of two materials with different hardness, cast into each other. The inner layer is stiff enough to hold its shape, and the outer layer soft enough to yield against the skin. A single-color, uniform silicone dildo has to compromise between the two properties: if you make it soft, it also becomes pliable; if you make it firm, the entire surface becomes firm. A two-layer construction avoids the compromise, because the stiffness and the softness are in different places in the same body.

The manufacturer describes the construction as a solid inner core enclosed by a soft, skin-like outer layer. What can be established purely technically is that the weight points in the same direction: 251 grams on a body that is 17.6 centimeters long and 3.5 centimeters in diameter is low for massive platinum silicone. The materials website for Silexpan explains why— it says the whole point of the material is that it makes it possible to manufacture large silicone products at significantly lower weight, which lowers shipping costs and makes the products easier to handle. So the low weight isn’t a coincidence; it’s the material’s stated business idea.

The comparison to a product made of a single material makes the difference concrete. Fun Factory states that The Boss, which is 17.9 centimeters long, weighs 265 grams in solid medical silicone—so 14 grams more than the Silexd model despite being roughly the same length and significantly thicker, 4.4 centimeters versus 3.5. That says something about how much weight the hollow or foamed core removes.

What is Silexpan made of?

Silexpan is not a trade name for silicone, and it’s worth being clear about that, because several shop texts mix up the terms. The material’s own website, run by CNEX—the same company behind Silexd—describes Silexpan as a patented composite material with properties similar to those traditionally used in the category, that is, silicone, PVC, TPE, and TPR, but with significantly lower production costs. The material is expressly used as filling behind a silicone skin.

The same page describes what the material makes it possible to control: flexibility, elasticity, weight, and density can be varied—from a sponginess like memory foam to different densities in different layers or parts of the same product. It’s exactly that description that Silexd’s dual-density construction is based on, and it also explains what the shops call the memory effect: that the product retains a shape it’s been pressed or bent into for a while before it reverts.

There’s one more thing the manufacturer does not publish, and it’s worth saying plainly: the chemical composition of the Silexpan core is not disclosed on either silexd.com or silexpan.com. We know that the core sits behind a silicone skin, that it isn’t in contact with the skin when the product is intact, and that the manufacturer labels the entire product as phthalate-free and pore-free. What we don’t know is which polymer family the core belongs to. As long as the skin is unbroken, it matters less—but that’s also the very reason why damage to the surface layer on this type of product should mean the product is discarded and not repaired.

Model 1, Model 2, or Premium Real Skin— which one is which for Silexd?

Silexd's naming is logical once you see the system, but shops rarely translate it. Three series are close to each other.

  • The Original, Model 1 — the series this text is about. Realistic shape with a pouch, a suction cup, and dual density in SILEXPAN® plus platinum silicone. In the manufacturer’s collection The Original, the model is listed in sizes 7, 8, 8.5, 9, and 10 inches, plus a separate Purple Edition in 7 inches.
  • The Original, Model 2 — the same material but a different shape. The smallest is called Model 2 6 inches and measures 15.4 centimeters total, of which 14.5 centimeters is insertable, with a diameter of 3.5 centimeters and a weight of 180 grams. The manufacturer’s specifications for this model state no suction cup in the base row, and the insertable length is almost on par with the total length—so it’s a model without a pouch.
  • Premium Real Skin, Model 1 (7") — the more expensive counterpart in the same size. 17.8 centimeters total, 13 centimeters insertable, 3.8 centimeters in diameter, and the material is listed as SILEXPAN® combined with liquid silicone instead of platinum silicone. The manufacturer does not publish a weight for this model.

The difference between The Original and Premium Real Skin is therefore not the size—they’re two millimeters apart in total length—but the type of silicone and the surface finish. If you want the largest possible insertable length relative to the total length, you should look at Model 2, which lacks a pouch and therefore doesn’t "use up" four centimeters on a base.

Material and build quality: platinum silicone over a Silexpan core

The material question is the only feature of an intimate product that can’t be compensated for with experience or care, and it determines whether the product will still be hygienic after five years. The manufacturer lists two materials for this model: SILEXPAN® in the core and platinum silicone on the surface. It’s a clearer statement than the category average, where "silicone" often stands alone without it being clear whether it applies to the entire product or only the surface.

What platinum silicone means in practice

Platinum silicone refers to the curing method, not to the fact that precious metal remains in the product. Silicone rubber can be cured in two main ways, and platinum-catalyzed two-component silicone is the method that leaves the fewest residual byproducts in the finished material. It’s the same family used in medical-device and food-adjacent applications, and that’s why the designation shows up again in product descriptions that want to signal higher material quality than regular peroxide-cured silicone.

However, the practically most important property here is not the curing but its non-porousness. Silexpans’s own materials page puts it plainly: silicone is considered the most hygienic material in this category, thanks to its flexibility, texture, non-porosity, durability, and the fact that it’s easy to clean. A non-porous surface can be cleaned, because there are no microscopic pores where residue can get trapped. That is the single most important property of a material that is meant to sit against mucous membranes, and that is why the material line weighs more heavily than almost every other line in a specification.

Silexd also states that the construction is non-porous and certified phthalate-free, and that the design is resource-efficient with recyclable materials of natural origin. The wholesaler SCALA, which sells the item on to European stores, describes the same product as phthalate-free, body-friendly, hypoallergenic, non-porous, and odorless. Another store specifies the material even further and calls it "phthalate-free and latex-free platinum silicone" as well as "body-safe and hypoallergenic".

Phthalates, latex, and why the material declaration is important

Phthalates are a group of plasticizers used to make plastic—above all plasticized PVC—flexible. The Swedish Chemicals Agency (Kemikalieinspektionen) 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 products. This specific product category is a recurring subject of oversight, because it contains plasticized materials against skin and mucous membranes.

Silicone does not need phthalate plasticizers to be soft—its softness comes from the polymer’s own structure—and that is why silicone, as a material specification, is in itself a better sign than almost any other entry in a product specification. That also makes the comparison with the nearest competitor in the same size interesting. ToyJoy’s Get Real Dual Density Dildo at 18 centimeters is built on exactly the same idea—soft exterior, firm core—but the wholesaler’s listing states the material as TPE. TPE is a thermoplastic elastomer that is softened in other ways than silicone and that does not have silicone’s non-porousness. So two products can be "dual density" and still belong to completely different material classes.

The latex statement is relevant for anyone who is allergic to latex. Latex allergy causes reactions on mucous membranes faster than on regular skin, and an intimate product is therefore exactly the kind of use where the statement matters. Here you should be careful about where the information comes from: latex-free is a store claim, not a wording the manufacturer uses on its own product page. The manufacturer writes phthalate-free and non-porous, but does not mention latex at all.

Measurements and weight: 17.6 centimeters—and three stores that say something else

The manufacturer’s dimensions are unambiguous and are also confirmed by the carton: the package is labeled 7" Model 1, 17.6 cm, and the graphics in the manufacturer’s own product gallery indicate a total of 17.6 centimeters, 13.6 centimeters insertable, and 3.5 centimeters in diameter. The wholesaler SCALA shows the same three dimensions and adds the product’s outer dimensions in three dimensions, 17.6 × 6.7 × 3.8 centimeters, where 6.7 centimeters is the suction cup’s width and 3.8 centimeters is the widest point of the body at the shaft.

So far, everything is straightforward. The problem arises at the retail level. Three of the seven shops list measurements other than the manufacturer’s, and the discrepancy is large enough to affect a purchase decision:

  • The listing sells the item under the heading "Silexd: Premium Silicone Dildo, 19 cm" and states the length as 18.8 centimeters, insertive length 13.5 centimeters, diameter 3.8 centimeters, and weight 276 grams.
  • One retailer calls it "Dual Density Dildo with shaft 18 cm" and states the overall length as 18 centimeters and insertive length as about 13 centimeters, but the diameter as 3.5 centimeters.
  • Another retailer has the correct overall length in its specification table, 17.6 centimeters, but states 14 centimeters insertable instead of 13.6—and also writes 17.8 centimeters in its own body text, so that’s a third value on the same page.

The discrepancy can be traced. The Danish retailer Loverland lists exactly the same EAN in its web address and shows the same set of figures as another shop listing—complete length 18.8 centimeters, insertion depth 13.5 centimeters, Ø 3.8 centimeters, and 276 grams—under a completely different item number, 05349600000. So it’s a distributor register that lives its own life in parallel with the manufacturer’s data, not another product variant. When the manufacturer and a store contradict each other, the manufacturer wins, and the right dimensions are 17.6 centimeters total and 13.6 centimeters insertable.

The weight information deserves the same treatment. The manufacturer states 251 grams. Another source states 0.33 kilograms, but it explicitly calls its figure "weight per unit" and presents it next to the packaging dimensions 26.9 × 10.7 × 9.4 centimeters and the information that 22 units fit in an outer carton. In other words, it’s a shipping weight with packaging, not the product’s weight. The 79-gram difference between 251 and 330 grams is the packaging, not the silicone. The other listed 276 grams belongs to the same deviating register as the length figure 18.8 centimeters and should be treated accordingly.

One last note about the packaging, because it’s unusually informative in this category. The manufacturer’s packaging graphics are labeled Eco Friendly, with a minimum of 72 percent natural materials and 100 percent recyclable—and the cardboard has a window that lets the entire product be seen without breaking the seal. It hardly decides a purchase, but it’s one of the few environmental details in the category that a manufacturer actually prints—and it’s verifiable when the package is sitting on the kitchen table.

Suction cup, harness compatibility, and thermoreactivity

A dildo without a motor has no positions to learn, and that’s why the entire usability question comes down to three things: how the base is secured, whether the product can be strapped into a harness, and what the material does when the temperature changes. Silexd publishes concrete information about all three, which isn’t a given in this price range.

The suction cup at 6.7 centimeters: what it can handle

The manufacturer lists the base as a suction cup with a 6.7-centimeter diameter and describes it as strong enough for hands-free use on any flat surface. The same measurements show up in the wholesaler’s product dimensions, 17.6 × 6.7 × 3.8 centimeters, where 6.7 centimeters is therefore the product’s widest point—the base is wider than the balls.

What can be established is that the relationship between the suction cup’s area and the product’s weight is favorable here. A suction cup with a diameter of 6.7 centimeters has an area of just over 35 square centimeters and is supposed to hold 251 grams. Compare that to Silexd’s own 8-inch model, which has exactly the same suction cup diameter, 6.7 centimeters, but weighs 352 grams—so that’s 40 percent more load on the same surface area. It’s one of the more concrete advantages of choosing the smaller model, and it’s never mentioned in any store text.

Suction cups work based on pressure difference and therefore need a surface that’s both smooth and airtight. Tile, the edge of a bathtub, laminate flooring, and mirrors work; untreated wood, texture-painted walls, and porous surfaces don’t. A slightly damp surface provides better grip than a completely dry one, because the water seals microscopic irregularities. If the base has stuck firmly, it should be released by lifting one edge and letting air in—pulling straight up loads the transition between the suction cup and the body, and that’s where a dildo of this type breaks first.

If compatibility with harnesses is clear from the manufacturer: the model is stated to be compatible with most harnesses and stands thanks to the suction cup base. Another listing specifies it for the retail stage and writes that it fits in most strap-on harnesses with a fastening ring. That’s reasonable because the base is a flat plate of 6.7 centimeters—but remember that the balls sit between the base and the shaft, and that it’s the shaft’s diameter at the base—not the suction cup’s—that determines whether the product can be passed through an o-ring.

How do you heat and cool a Silexd dildo?

Thermoreactivity is the function Silexd markets most aggressively, and it is also the one that is easiest to misunderstand. The manufacturer describes it like this: the material responds to temperature—heat the product under water for a softer, more yielding feel, or cool it down for extra firmness. The function graphic in the manufacturer’s own gallery puts it as “softer with heat, harder when cold.”

The manufacturer does not publish exact time limits on its product page, but four of the seven online shops state the same two values, and they are worth noting because they set an upper limit: at most 30 seconds in the microwave and at most 2 minutes in boiling water. The shops all use the exact same wording. For cooling, the listings specify cold water or a refrigerator without a time limit.

Two things are worth thinking about before you try it. The first is that heating a product that is meant to contact mucous membranes always requires that you check the temperature against the inside of your wrist before use—a dildo heated in boiling water holds onto the heat in the core longer than the surface suggests, precisely because the core is a different material than the skin. The second is that the microwave oven is the more risky of the two methods, since the heat is distributed unevenly. Boiling water provides a more even heating and is therefore the method that is easier to control.

What can be established in principle is that thermoreactivity is not a gimmick, but a direct result of the material selection. All elastomers get softer when they’re heated and stiffer when they’re cooled; the difference here is that, according to the manufacturer, the composite construction makes the effect big enough that it is usable. How many Shore degrees that difference corresponds to does not publish Silexd—no Shore hardness specification is shown on the manufacturer’s site. In the store listing, the hardness is described as “medium,” which is a relative description without a measured value.

13.6 centimeters insertable — what the number actually means

The difference between total length and insertable length is four centimeters on this model, and those four centimeters are the balls and the suction-cup base. That is the number that should be compared between products, not the total length, and it is also the number stores most often omit from the headline. A “19 cm dildo” with balls may very well have a shorter insertable length than a “16 cm dildo” without.

Silexds own series illustrates the point well. Model 1 7" gives 13.6 centimeters insertable length out of 17.6. Model 1 8" gives 17 centimeters out of 20.5 — meaning 3.4 centimeters more in insertable length for 2.9 centimeters more total length, and at the same time a full centimeter more in diameter, 4.5 vs 3.5. Model 2 6" gives 14.5 centimeters out of 15.4, meaning more insertable length than the 7-inch model even though it is 2.2 centimeters shorter overall — simply because it has no ballsack that takes up space.

The diameter of 3.5 centimeters corresponds to a circumference of just under 11 centimeters. That places the model in the lower half of the realistic segment — Fun Factory The Boss is at 4.4 centimeters, ToyJoys Get Real is in the same length class at 4 centimeters, and Silexds own 8-inch model at 4.5. So if you choose this model, you’re choosing the narrowest of the compared ones, which is relevant both for beginners and for someone who wants something that works in a harness without stretching the O-ring.

Cleaning, lubricant, and storage

The care question is short and clear for a product without electronics, but two of the sub-questions have answers that differ from what the shop texts suggest.

Waterproof without IP rating: what the manufacturer actually says

The manufacturer’s product page labels the model with the symbol Waterproof, and the function graphics in the gallery spells it out: waterproof and easy to clean. Some shop listings go further and state "100 % waterproof".

Here you need a clarification. Silexd does not publish an IP rating for this model — neither IPX7 nor any other enclosure class is specified. That, in itself, is completely reasonable: IP rating according to the IEC 60529 standard applies to the enclosure of electrical equipment, and this product contains no electrical parts. A solid molded body with no openings, buttons, or charging contact has nothing to seal. The difference vs a vibrator is therefore fundamental, not a difference in degree: a dildo without electronics is waterproof by design, not by rating.

Practically speaking, that means the whole product can be rinsed under running water, works in the shower and bathtub, and can be boiled — the manufacturer describes heating under water itself as an intended function. What still needs to be kept in mind is the temperature limits that the shops state, and that the suction cup is the only part where water can remain standing if the product is put away with the base down on a flat surface.

Which lube works with a Silexd dildo?

Water-based, and it’s not a recommendation but a material question. One retailer puts it most sharply: use only water-based lube for Silexd dildos, because silicone- and oil-based lubes destroy the material. Another retailer states the same thing in its specification line for recommended lube.

The reason is chemical. A silicone-based lubricant consists of the same family of polymers as the silicone surface, and the two seek each other out. Over time, the outer surface layer softens, becomes tacky, and finally porous—and a porous surface can no longer be cleaned properly; it can only be replaced. This is especially serious for a double-density product, because a damaged surface means the inner material is exposed. Oil-based products such as coconut oil also leave behind a film that is difficult to remove and that builds up over time.

The rest of the cleaning is simple: the manufacturer states mild soap and water or a cleaning agent intended for intimate products. Rinse the product in lukewarm water after every use, rub the entire surface including the folds at the scrotum and the underside of the suction cup, and let it air-dry before putting it away.

Storage and lifespan

Silicone surfaces attract dust and lint, and this product does not include a storage pouch in the delivery—according to the manufacturer’s contents list, the product includes an instruction sheet, and nothing else. A cotton bag or the original box is therefore not a luxury but the practical way to avoid having to wash the product twice.

Do not let the product lie against other sex toys made of soft plastic. Softened PVC and some TPE materials can transfer onto silicone during longer contact and leave sticky marks that won’t go away. This is one of the most common ways to ruin a silicone product that otherwise would have lasted for years.

The lifespan of a product without electronics is determined by the surface, not by a battery. What matters is whether the silicone skin stays completely intact. If a crack, cut, or puncture occurs, the product is used up, because the core is no longer encapsulated—and as stated above, the manufacturer does not publish the composition of the core material. That’s a reason to never use sharp objects near it and not to store it compressed under pressure.

Silexd Model 1 7 inches compared with the alternatives

Four comparisons are relevant: two within Silexd’s own range, and two against other brands in the same size class. All information below comes from the respective manufacturer’s or wholesaler’s own specifications, and we don’t have price data for this market.

Against Silexd Model 1 8 inches — 3.4 centimeters more, 101 grams heavier

Silexd’s next step up is the Model 1 8". The manufacturer states the total length is 20.5 centimeters, the insertable length is 17 centimeters, the diameter is 4.5 centimeters, and the weight is 352 grams—with the same suction cup of 6.7 centimeters and the same material combination. The list price is 44.90 euro versus 34.90 euro for the 7-inch model.

The difference isn’t just length. The diameter goes from 3.5 to 4.5 centimeters, meaning it’s almost 29 percent thicker, and in practice that’s a bigger change than the 3.4 extra insertable centimeters. At the same time, the same suction-cup diameter has to support 101 grams more. What can be established is that the 7-inch model has the better ratio between base and mass, and that the 8-inch model is a step up in two dimensions at the same time—which rarely shows up in a shop headline that only states the length.

Compared to Silexd Premium Real Skin Model 1 — same size, different silicone

The most interesting internal comparison is Premium Real Skin Model 1 (7"), because it’s within two millimeters in total length: 17.8 centimeters versus 17.6. The insertable length, however, is shorter, 13 centimeters versus 13.6, and the diameter is thicker, 3.8 centimeters versus 3.5. The material is listed as SILEXPAN® combined with liquid silicone instead of platinum silicone, and the surface is described with a hyper-realistic skin finish.

Two things are worth knowing before you pay more for the Premium line. The manufacturer does not publish a weight for Premium Real Skin Model 1, which makes it impossible to compare how much mass is behind the suction cup. And the insertable length is actually shorter than on the cheaper model, even though the total length is greater—every bit of the added length sits in the base. The one who chooses insertable length gets more for their money in The Original; the one who chooses surface finish gets it in Premium Real Skin.

Compared with ToyJoy Get Real Dual Density 18 cm — silicone vs TPE

The closest external competitor in the same size is ToyJoy’s Get Real Dual Density Dildo, the 18-centimeter model with balls. The wholesale data is almost eerie in its similarity: total length 18 centimeters versus Silexd’s 17.6, insertable length 14 centimeters versus 13.6, packaging weight 0.32 kilos versus 0.33, packaging 27 × 15 × 8 centimeters versus 26.9 × 10.7 × 9.4, and both made in China.

Two things set them apart, and both matter. The first is the diameter: ToyJoy states 4 centimeters insertable versus Silexd’s 3.5. The second, and more important, is the material. The ToyJoy model is listed as TPE, the Silexd model as platinum silicone over a Silexpan core. TPE is cheaper to manufacture and easy to cast in dual density, but it isn’t non-porous in the same way as silicone, and it ages differently. What can be established is that two products can carry exactly the same selling points—dual density, soft outside, firm core, balls, suction cup—and still fall into different material classes. Read the material row, not the headline.

Compared with Fun Factory The Boss — solid silicone vs composite

The last comparison is against a product that deliberately takes the opposite route. Fun Factory states the dimensions for The Boss as 17.9 centimeters and Ø 4.4 centimeters, the weight as 265 grams, and the material as 100 percent medical silicone, described as pore-free and hypoallergenic. The price is 39.95 euros versus the regular price of 59.90 euros, meaning it is below the manufacturer’s list price for the Silexd model, which is 34.90 euros.

The Boss is therefore almost the same length but a full centimeter thicker—and yet only 14 grams heavier. That’s the material difference in a nutshell: a solid silicone product of that size would have weighed significantly more, suggesting that Fun Factory also uses a hollowed or lightened construction. The difference from Silexd is that Fun Factory states a single material throughout, while Silexd states two and only lists the composition on the outside.

Fun Factory, on the other hand, lacks a shaft on this model and markets an extra-thin base to get closer to the shaft. Silexd has a shaft and a wider suction cup. If you want realistic anatomy with a shaft and the lowest possible price, Silexd is the choice; if you want a single declared material type throughout and a base built for the shaft, Fun Factory is the one.

Any price differences come down to how a shop sets its margin, so it pays to compare before you pay.

The prices in the table above are updated when the shops’ product feeds are updated, but always check the final price at checkout. Shipping costs are added by some stores under a certain order value, and that can narrow or widen the differences between listings once you account for the total cost.

Who is it for—and who is it not for?

It’s for you if you want a realistic shape with a shaft and a suction cup in a material that can be cleaned properly, at a price that’s well below what massive premium silicone costs. It’s for you if you want the slimmer version—3.5 centimeters in diameter is the narrowest of the four compared models—and for you who want to be able to use the product hands-free against tile or in a harness. The fact that it only weighs 251 grams is also a direct advantage for the suction cup and for the person using a harness for longer stretches.

The temperature function is the feature most likely to determine the purchase one way or the other. If you want to cool or warm the product before use, this design is built for that, and the manufacturer describes it as an intended function. If it’s not something you’re going to do, you’re paying for a feature you won’t use—and then there are solid silicone alternatives with a single declared material type.

It’s not for you if you want the longest possible insertable length—here, Silexd’s own Model 2 6" is a better buy even though it’s shorter overall, and Model 1 8" is a better buy if the thickness is also supposed to be greater. It’s not for you if you require that the entire material composition be disclosed, since the chemistry of the Silexpan core isn’t published. And it’s not for you if you want a manufacturer warranty with a stated guarantee period, because Silexd offers none.

One more thing belongs in the decision. The store product names for this specific item are unreliable—the same EAN is sold as "17,6 cm", "18 cm", and "19 cm" in three different shops. If you decide based on a headline, you’ll end up comparing the wrong products with each other. If you decide based on the EAN number and the manufacturer’s measurements, you’ll get the right item regardless of which of the seven shops you use for comparison.

Warranty, warranty claims, and right of withdrawal

Here is a statement that is unusually clear: SILEXD does not offer any voluntary manufacturer’s warranty for the specified period. Instead, the manufacturer’s terms refer to the statutory warranty for liability for defects under Spanish and European consumer law, and state that in the event of a defect they offer repair, replacement, a price reduction, or a refund, depending on what is appropriate. This is not the same as saying that the product lacks protection — but there is no five-year warranty or ten-year warranty to compare with in this category, and it should be factored in when the model is compared with brands that commit to their own warranty period.

The manufacturer’s return terms are also worth knowing even if you shop in the EU/EEA, because they reflect how the entire category works. Silexd only accepts returns where the hygiene seal and original packaging are intact. If the seal is broken, the item can’t be returned—even if it’s unused—since, under EU rules, sealed goods that aren’t suitable for return for health or hygiene reasons are exempt from the withdrawal right once unsealed. In the event of an incorrect, damaged, or incorrectly delivered item, EU rules provide a legal guarantee for defects: the seller is liable for defects that exist at delivery and appear within at least 2 years; the manufacturer covers return shipping, and the refund is issued within 14 days after the returned item is received.

When buying from a business online in the EU/EEA, you generally have a 14-day right of withdrawal. The 14-day period starts when the goods are received. Under EU rules, sealed goods that are not suitable for return for health or hygiene reasons are exempt from the right of withdrawal once unsealed. The seller is still liable for defects that exist at delivery and appear within at least 2 years (the legal guarantee). Rules outside the EU differ.

A final piece of advice from the withdrawal/defect rules: save the cardboard box until you’re sure the product is intact. The manufacturer’s packaging has a window that allows you to inspect the product without breaking the seal, and a casting defect or a crack in the surface layer is usually visible right away. If you notice the defect before the seal is broken, you still keep the right of withdrawal; if you notice it afterwards, the withdrawal right is limited, but the legal guarantee still applies—defects that exist at delivery and appear within at least 2 years can be claimed.

Frequently asked questions about the Silexd Silex-D Dual Density Silicone Dildo 17,6 cm

How long is the Silexd Silex-D Dual Density Silicone Dildo really?
The manufacturer states that the total length is 17.6 centimeters and the insertable length is 13.6 centimeters, and the same figures are printed on the box, which is labeled 7" Model 1, 17.6 cm. Three stores provide other values: one writes 18.8 centimeters under the heading 19 cm, another writes 18 centimeters, and a third lists 14 centimeters insertable plus 17.8 centimeters in its own body text. The differing set of measurements can be traced to a distributor register — the Danish retailer Loverland lists exactly the same EAN with the same figures. When the manufacturer and a store contradict each other, the manufacturer’s values apply: 17.6 centimeters total, 13.6 insertable.
What is Silexpan, and is it the same thing as silicone?
No. Silexpan is a patented composite material from CNEX, the same company that owns the Silexd brand, and it is used as a filler behind a skin of silicone. The material’s own website describes it as a material with properties similar to silicone, PVC, TPE, and TPR, but at a significantly lower production cost, and whose main benefit is that large silicone products can be manufactured with much lower weight. The surface of this model, however, is genuine platinum silicone according to the manufacturer. The core’s exact chemical composition is not published by either silexd.com or silexpan.com.
What does dual density mean, and how does it differ from a regular silicone dildo?
Dual density means that the product consists of two materials with different hardnesses molded into each other: a firm inner core that holds its shape and a soft outer layer that yields against the skin. A dildo made from a single material has to choose between being soft and flimsy or firm across the entire surface. Weight shows the effect: the Silexd model weighs 251 grams at a length of 17.6 centimeters and a diameter of 3.5 centimeters, while Fun Factory lists 265 grams for The Boss, which is 17.9 centimeters long and has a full 4.4 centimeter diameter in solid medical silicone.
How do you heat or cool it, and for how long?
The manufacturer describes heating under water for a softer feel and cooling for extra firmness, but it does not state any times on its product page. Four of the seven stores, however, list the same two limits: at most 30 seconds in the microwave or at most 2 minutes in boiling water. For cooling, it’s cold water or a refrigerator, with no time limit. Always check the temperature against the inside of your wrist before use, since the core is a different material than the skin and retains the heat longer than the surface suggests.
Is the Silexd Silex-D waterproof, and does it have any IP rating?
The manufacturer marks the model as waterproof and writes in its product graphics that it is waterproof and easy to clean. One shop listing states “100% waterproof” in the store setting. No IP rating is published, though—and that makes sense in itself: IP rating according to IEC 60529 applies to the enclosure of electrical equipment, and this product contains no electrical parts. A solid cast body without buttons, openings, or a charging connector has nothing to seal. The whole product can therefore be rinsed under running water and can even be boiled within the time limits that the store listings state.
Which lubricant works with Silexd?
Only water-based. One shop directly states that silicone- and oil-based lubricants damage the material, and another store lists water-based as the recommended lubricant in its specification. Silicone-based lubricant consists of the same family of polymers as the silicone surface and softens it over time until it becomes porous—and on a dual-density product, a damaged surface means the internal material is exposed. Oil-based products such as coconut oil also leave a film that’s difficult to remove.
What warranty applies to Silexd, and what rights do you have in the EU/EEA?
Silexd does not offer any voluntary manufacturer warranty with a specified period. Instead, the manufacturer’s terms refer to the statutory liability warranty under Spanish and European consumer law and specify repair, replacement, price reduction, or refund if there is a defect. If you buy online in the EU/EEA, you generally have a 14-day right of withdrawal, starting when the goods are received. However, sealed goods that are not suitable for return for health or hygiene reasons are exempt from the right of withdrawal once unsealed. Under EU rules, the seller is liable for defects that exist at delivery and appear within at least 2 years (the legal guarantee). In practice, the right of withdrawal is limited for hygiene products whose seal has been broken—the manufacturer’s own return policy applies exactly the same rule and only accepts returns with an unbroken hygiene seal.
Why does the price differ by 67 percent between the stores for the same product?
No shop in our data sells the same item with EAN 8433345220277 in this market.
