Toy Joy Glass Worxx Crystal Cock: review

Toy Joy Glass Worxx Crystal Cock in brief — here’s what you get

Glass Worxx Crystal Cock is a glass dildo from the Dutch Toy Joy. According to the manufacturer’s own safety manual, Toy Joy is a registered trademark and a commercial designation for Scala 2.0 B.V., and the address in the terms is Bijsterhuizen 3151 in Wijchen. The product is completely manual: it contains no motor, no battery, no electronics, and no charging port. The entire product consists of a single material, and that is, in practice, the whole basis for the assessment — for a product without moving parts, the material, the geometry, and the documentation are everything you have to go on.

The specification looks like this. The manufacturer lists high-quality borosilicate glass as the material and an insertable length of 15 centimeters. Four stores consistently state a total length of 17.5 centimeters and a largest diameter of 3 centimeters. The manufacturer describes the shape as realistic, with a rounded top and balls at the base, and the product is stated to be intended for both vaginal and anal use. In this market, no shop in our data sells it.

This review is about the clear variant with EAN 8713221845337, the manufacturer’s article number 10620-CLEAR. The number has been checked against the manufacturer’s own product page, where the item is listed with the exact GTIN value. It’s worth doing that check yourself if you’re comparing prices, since the Glass Worxx series includes a dozen or so articles with similar-sounding names — Crystal Jewel, Crystal Heart, Sparkle G-Spot, G-Spot Gemstone, and several more — all of which are made of glass and all of which are in the same price range.

What Glass Worxx is, and where Crystal Cock fits in the series

Glass Worxx is Toy Joy’s glass collection. The manufacturer describes it as a premium series in high-quality borosilicate glass, hypoallergenic, body-safe, and intended for temperature play. The same marketing text is repeated verbatim at the top of every product page in the series, which says something important: the series description is the same, not product-specific. What actually differentiates the items is in the short paragraph below, and for Crystal Cock it’s the shape — smooth surface, rounded top, and a realistically inspired body with balls.

Crystal Cock is the series’ penis-shaped model. It differs, for example, from Crystal Heart, which is an anal dildo with balls and a heart-shaped handle, and from Sparkle G-Spot, which is a curved wand for G-spot stimulation. So choosing between them is not about quality or material— they are made of the same glass and cost about the same—but only about which shape you want. It is an unusually honest, series-based mindset in a category where manufacturers are happy to pretend that every new shape is also a technical advancement.

Crystal Cock or Crystal Dildo—what is the product actually called?

Here is a detail worth pointing out, because it makes the product hard to search for. The manufacturer’s web shop calls the item Crystal Cock. The body text on the same page calls it Crystal Dildo. And on the packaging, which can be seen in the manufacturer’s own product image, it says CRYSTAL DILDO under the Glass Worxx by ToyJoy series logo. Three names for the same article, all from the manufacturer itself.

In the four shops we checked, it’s listed under different names. The practical advice is therefore simple: search by the EAN number, not by the name. The number 8713221845337 is the same in all four shops and with the manufacturer, and it’s the only thing that reliably points to exactly this item.

Dimensions: 17.5 centimeters total and 15 centimeters insertable

The question about dimensions is interesting here, because the manufacturer and the shops each provide half. The manufacturer does not publish a total length on the product page. The only measurement that comes directly from Toy Joy is shown in the manufacturer’s own product image, where a line along the shaft is marked "Insertable Length: 15 cm". The total length of 17,5 centimeter instead comes from the shops—and all four agree there, which is unusual enough to be worth noting.

If you add the two details together, you get a non-insertable part of 2.5 centimeters. The “balls” section at the base—meaning the part intended to stay outside the body and function as a grip. The proportion says something about the product: the grip is short relative to the shaft, and it’s a design choice that favors reach over hand control.

The diameter at 3 cm—what that corresponds to

All four shops list the largest diameter as 3 centimeters. One shop specifies it as "Diameter (max) 3,00 cm", which is the clearest wording of the four—it’s the product’s thickest point, not an average along the shaft. The manufacturer does not publish any diameter at all.

A three-centimeter diameter corresponds to a circumference of just under 9.5 centimeters. That places Crystal Cock in the middle layer: it’s thicker than a typical G-spot shaft but narrower than the items that are marketed as large. What makes this figure more relevant here than on a silicone product is that glass doesn’t give. A silicone dildo with a 3-centimeter diameter can be compressed a bit; a glass dildo with the same measurements cannot. In practice, that means that 3 centimeters in glass feels like more than 3 centimeters in silicone, and that is the single most important thing a first-time buyer of glass products should take into account.

One retailer explicitly states the firmness as “Hard” in its quick facts. It’s a store claim and not a manufacturer claim, but it’s hard to dispute for a solid piece of glass.

The weight no one publishes

Toy Joy publishes no weight for Crystal Cock, and none of the four shops we checked does either. It’s the biggest gap in the specification, and it’s more significant on a glass product than on a battery-powered one.

The reason is that the weight of a solid glass body isn’t a matter of convenience—it’s a matter of use. The weight is part of how the product feels; it determines how much force the wrist needs to apply to control it, and it determines how much kinetic energy the product has if it’s dropped. On a battery-powered silicone product, weight is mostly just information; here, it would have been decision-making support. The fact that it’s missing is a real minus in the documentation, and it affects the rating.

What can be concluded from the geometry is that a solid glass cylinder of just under 15 centimeters with a 3-centimeter diameter, plus a ball section, is clearly above what you associate with a silicone dildo of the same size. Exactly how much above can’t be said without a published figure, and that’s why it isn’t stated here either.

Material: borosilicate glass, and what it actually means

The material is the only thing the manufacturer says something definite about, and it’s also the characteristic that matters most. Toy Joy states high-quality borosilicate glass for the entire series and describes it as hypoallergenic and body-safe. On the packaging, the marking Safety Glass is shown, and in the manufacturer’s product image, Body Safe, Hypoallergenic, Easy To Clean, and Temperature Play are repeated as four of five icons.

What is borosilicate glass, and how is it different from ordinary glass?

Borosilicate glass is made according to SCHOTT—one of the largest manufacturers of the material—from two main components: silicon oxide and boron oxide. The addition of boron is the whole point. It gives the glass a low thermal expansion coefficient, and low thermal expansion means the material moves little when the temperature changes. That is why, according to the same source, borosilicate glass has noticeable resistance to thermal shock and temperature fluctuations, and that is also why laboratory glassware and oven molds are made from it.

Ordinary window and bottle glass is lime-soda glass. It expands more when heated, which means that stresses build up in the glass body when one part of the glass is heated faster than another. SCHOTT also states that borosilicate glass has higher hydrolytic resistance and better resistance to acids than lime-soda glass—meaning it holds up better against water and chemicals over time. For a product that is meant to be rinsed in hot water hundreds of times, this is a relevant difference, not a technical curiosity.

The designation is also standardized. The international standard ISO 3585, Borosilicate glass 3.3 — Properties defines the properties of the borosilicate glass 3.3 material class, and it applies in its third edition, established in 1998. Here, however, there is an important reservation: Toy Joy never states that the glass in Crystal Cock is borosilicate glass 3.3, only "high-quality borosilicate glass". It is a material family, not a classification. Without a specified class, no numerical values for expansion or temperature tolerance can be derived for this particular product, and therefore there are no such numbers in this text.

Non-porous material: the only hygienic property that can’t be compensated for

Glass is non-porous. That means the surface lacks microscopic cavities where residues, moisture, and bacteria can remain, and that is why the surface can actually be made clean rather than just rinsed. It is the most important property of a material that should come into contact with the mucous membrane, and it cannot be compensated for with either care or habit.

The difference versus soft materials is fundamental. A porous surface absorbs lubricants and bodily fluids into the material itself, and once it has done so there is no cleaning method that gets them out again—the product is used up but still looks intact. Glass has none of that problem at all. A glass dildo that is intact is as clean after five years as it is after the first use, provided it is washed. That is why this product category has a completely different lifespan profile than the rest of the assortment: there is no best-before date—only a risk that it breaks.

Phthalates, plasticizers, and why glass sidesteps the issue

Phthalates are a group of softeners that are used to make plastic—above all, soft 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. Intimate products are recurring subjects of supervision, because the category has traditionally contained a lot of soft plastic against skin and mucous membranes.

Glass sidesteps the whole question. A massive glass product needs no softeners, because it is not supposed to be soft. There is no polymer that can be broken down, no softener that can migrate out of the material, and no surface treatment that can be worn away. The manufacturer’s description “hypoallergenic” thus becomes unusually easy to take seriously—not because Toy Joy has shown anything, but because the material class itself does not contain the substances that cause the problems. It is the only point in the entire specification where a glass product wins outright against both silicone and TPE.

Use: grip, angle, and what the shape does

The manufacturer describes the shape as realistically inspired, with a smooth surface, a rounded top, and balls at the base, and states that the product is intended for both vaginal and anal use. What can be established from the manufacturer’s own images is that the shaft is straight and evenly thick over almost its entire length, that the transition to the top is marked rather than soft, and that the ball section at the base sits at a clear angle in relation to the shaft.

This geometry has two consequences. The first is that the 15 insertable centimeters in practice are evenly thick—there is no taper that makes the first centimeters easier. The second is that the marked edge under the top is the only shape detail that creates variation in the pressure pattern. On a glass product, such an edge becomes clearer than on a silicone product, because the material does not give anywhere.

The ball base as a grip—and why it isn’t a stop base

The ball section at the base is what holds the product in your hand. It is 2.5 centimeters long, calculated as the difference between retailers’ total length and the manufacturer’s insertable length, and it is angled in relation to the shaft, which gives your wrist something to rest against.

It’s important to distinguish between a grip and a stop base. A stop base is a wide, flat flange that physically prevents the product from going in too far—this is a safety requirement for anal use, since the rectum, unlike the vagina, has no natural end point. The ball base on Crystal Cock is a grip: it is wider than the shaft, but it is rounded and angled rather than flat and straight across. The manufacturer nowhere states that the base is a stop base, and it shouldn’t be treated as one.

Can Crystal Cock be used anally?

The manufacturer explicitly states that the product is suitable for both vaginal and anal use. So it’s not an assumption—it’s Toy Joy’s own statement, and it’s unambiguous.

But the statement needs to be read together with the shape. For anal use, it’s crucial that the product is held in your hand at all times, precisely because the ball base works as a grip and not as a barrier. The smooth surface of the glass, combined with plenty of lubricant, makes the product easy to lose your grip on, and that’s a combination that deserves respect. If what you’re mainly looking for is a glass product for anal use, then the Crystal Heart Anal Dildo in the series is the item Toy Joy itself points out for that purpose—it’s shorter, has balls along the entire body, and a heart-shaped handle that is noticeably wider than the shaft.

Temperature play: how to heat and cool it without taking risks

Temperature play is the argument Toy Joy highlights most clearly for the entire Glass Worxx series. The manufacturer formulates it as meaning that the product can be warmed for a sensual feel or cooled for a tingly sensation, and Temperature Play is one of the icons both on the packaging and in the product image.

The physics behind it is simple, and makes glass a better material for this than silicone: glass conducts heat better and retains it longer. A warmed glass body releases heat to the skin for significantly longer than a warmed silicone product of the same size, and a chilled glass body feels cold for longer. That’s why the function in practice only works for glass and metal.

How do you heat a glass dildo safely?

The method that works is a water bath with lukewarm to hot tap water, where the product is allowed to sit for a few minutes and the temperature is allowed to rise slowly. The manufacturer describes cleaning with warm water as normal care, which indicates that warm tap water is not a problem for the material.

What should be avoided is sudden temperature differences. Even though borosilicate glass, according to SCHOTT, resists temperature shock considerably better than regular glass, the resistance isn’t infinite, and the manufacturer publishes no limit specifically for this product. Therefore, putting a fridge-cold product directly into hot water, or holding it under a hot-water tap at full pressure, are unnecessary risks. Always check the temperature against the inside of your forearm before using the product—glass that feels comfortable against your palm can be too hot for mucous membranes.

Chilling in the fridge—and why the freezer is a bad idea

You chill it in the fridge, not in the freezer. A fridge keeps it at a few degrees above zero and provides a consistent, gentle cooldown that takes twenty minutes. A freezer takes the product to twenty degrees below zero or lower, which on the one hand means a much larger temperature range compared to body temperature when it’s used, and on the other hand involves a real risk of cold injury to the mucous membrane during longer contact.

A clean, practical tip that applies both ways: put the product in a clean plastic bag or in a lidded container before it goes into the refrigerator. It’s a hygiene measure, not a material measure, and it means you don’t have to wash the product twice.

The temperature limits the manufacturer does not publish

Toy Joy does not publish either a maximum or a minimum permitted temperature for the Glass Worxx series. There is no product-specific manual, and the general safety manual that is on the manufacturer’s manuals page explicitly applies to motor-driven intimate products—so it does not apply to this item. No stores we reviewed indicate a limit either.

It’s a conspicuous gap in this particular case, because temperature play is the functional argument the manufacturer itself markets most aggressively. The entire selling point is built on the product being exposed to temperature changes, and the only parameter that determines how far you can go is not published. What’s left, therefore, are general recommendations about moderation rather than manufacturer-provided limit values, and you should be aware of that before you experiment.

Lubricant: the only product category where glass wins outright

The manufacturer writes that Crystal Cock is compatible with all types of lubricants. This isn’t just a throwaway line—it’s a real and unusual advantage, and it’s worth understanding.

For silicone products, you should avoid silicone-based lubricants, because they break down the silicone surface over time and make it porous. A porous surface can no longer be cleaned properly—it can only be replaced. Oil-based products also leave behind a film that’s hard to remove. With glass, none of these problems apply. Glass doesn’t react with silicone oil, with vegetable oils, or with hybrid products. So you can use the lubricant that works best for you without having to read the ingredients list first.

That also means a glass product works well with silicone-based lubricant for anal use, where this type is often preferred because it lasts longer and doesn’t dry out. That option isn’t available with a silicone dildo. The exception that still applies is condoms: oil-based lubricants break down latex, so if you use a condom over the product—which is a completely reasonable way to simplify cleaning—the usual rules apply again.

Cleaning, storage, and checking before use

The manufacturer’s care instructions are short and clear: clean with warm water and mild soap or a sex toy cleaner. The stores repeat the same thing and add that the product should be dried thoroughly and stored dry. Since the glass is non-porous, nothing beyond that is needed—there are no seams, no buttons, and no charging contact where residue could get left behind.

Dishwasher-safe or boiling?

Toy Joy states nowhere that Crystal Cock is dishwasher-safe, can be boiled, or can be disinfected in other ways using heat. The manufacturer’s only instruction is warm water and mild soap. The absence of an approval is not a ban, but it is also not permission, and for a product without published temperature limits there’s no reason to guess. Stick to warm tap water and soap, and you’ll do exactly what the manufacturer actually describes.

The storage question is more about durability than about hygiene. The manufacturer does not state that any storage bag is included, and the stores do not list one either. A soft pouch or your own box is therefore something you’ll need to arrange yourself, and with a glass product, it’s not a luxury—it’s what keeps it away from other hard objects in the drawer.

Check the glass before each use

This is the routine that’s missing from almost all product texts about glass dildos, and it’s the most important one. Look at and feel along the entire product before each use: look for chips in the surface, for thin cracks that catch the light at a different angle than the rest of the glass, and for cloudy spots. Run your finger around the top and around the ball area—these are the areas that receive impact if the product is dropped.

If you find anything—throw the product away. A chip on the edge of a glass surface becomes sharp, and a crack in a solid glass item is never made better by itself. It’s a simple precaution for this product, and it’s also the real answer to why glass has a durability profile that’s different from everything else in the category: the product is either flawless or unusable—never anything in between.

Documentation: what Toy Joy publishes and what’s missing

The summary isn’t flattering. From the manufacturer you get the material, the insertable length, intended use, lubricant compatibility, care instructions, the EAN number, and the item number 10620-CLEAR. That’s it.

What is inte published by Toy Joy is total length, diameter, weight, package dimensions, contents of delivery, temperature limits, glass classification, and warranty period. Eight lines where competitors often have numbers. The manufacturer’s manual page contains three documents, and none of them apply to glass products—the general manual is titled as safety and user instructions for motor-driven intimate products, and its sections on charging, batteries, and water resistance are, by definition, not applicable here.

A detail like this belongs in the documentation chapter. One retailer lists the item number as SC4607-1, while the manufacturer lists 10620-CLEAR. There’s no contradiction about the variant—the EAN number is identical in both sources, and the EAN is what identifies the item—but it’s an example of how many parallel number series circulate for the same product. It’s also yet another argument for comparing by EAN when you’re looking for the best price.

Crystal Cock compared with the alternatives

Three comparisons are relevant: against Toy Joy’s own anal model in the same series, against another competing glass series, and against the material that otherwise dominates the category. All measurements below come from the respective manufacturer’s own information or from the shops’ product pages, and it’s clear which is which.

Against ToyJoy Glass Worxx Crystal Heart Anal Dildo — same glass, different information

Crystal Heart Anal Dildo is the sister model in the series. The manufacturer lists the same borosilicate glass, the same series description, and EAN 8713221845351, item number 10622-CLEAR. The difference lies entirely in the shape. In this market, no shop in our data sells the Crystal Cock.

The listing states that Crystal Heart has a total length of 15.00 centimeters, an insertable length of 11.50 centimeters, and a largest diameter of 3.00 centimeters. Compared with Crystal Cock’s 17.5 and 15 centimeters, respectively, it’s therefore 2.5 centimeters shorter overall and 3.5 centimeters shorter in the insertable part, with identical thickness. The manufacturer describes it as designed specifically for anal use, with smooth rounded balls that build up the sensation gradually, and a heart-shaped handle for comfort and control.

The conclusion is straightforward. If you’re looking for a glass product primarily for anal use, Crystal Heart is the one Toy Joy itself highlights, and its heart-shaped handle is a significantly clearer grip than Crystal Cock’s ball section. If you’re looking for reach and an evenly thick shape, Crystal Cock is the one that gives you 3.5 centimeters more to work with—at the same price.

Against Pipedream Icicles No. 8 — completely different documentation.

Icicles is the most widespread glass series in shops, and Icicles No. 8 is the model that’s closest to Crystal Cock in format. The listing gives it as having a total length of 17.50 centimeters, an insertable length of 14.50 centimeters, and a largest diameter of 3.50 centimeters. The measurements are therefore almost identical to Crystal Cock’s, except for thickness: 3.5 versus 3.0 centimeters.

Two differences are worth weighing. The first is manufacturing. Pipedream states that each Icicles item is hand-blown, which means the specimens differ slightly from each other and that the pattern is unique for each product. Toy Joy says nothing about the manufacturing method for Glass Worxx. The second is the warranty, and there the difference is concrete: Pipedream states a one-year warranty on its product page for Icicles No. 8, while Toy Joy publishes no warranty period at all. Both manufacturers describe their glass as hypoallergenic, non-porous, and body-safe.

The choice comes down to a half centimeter more in thickness and a published warranty for Icicles, versus a published insertable length and a slightly narrower shaft for Crystal Cock. If you want the better documented of the two, Icicles wins; if you want the narrower one and the one whose manufacturer actually states how much goes in, Crystal Cock wins.

What’s the difference between a glass dildo and a silicone dildo?

This comparison doesn’t apply to a single product; it’s a choice point, and it’s usually the one that determines the purchase. Both materials are non-porous, and both can therefore be cleaned properly. That’s where the similarities end.

Glass wins on three points. It tolerates all types of lube, while silicone shouldn’t be combined with silicone-based lube. It works for temperature play, which silicone in practice doesn’t do, because it conducts heat worse and loses temperature quickly. And it doesn’t age: there’s no polymer that breaks down, no surface that becomes sticky, and nothing that changes over time. An entire glass product is identical to a new glass product.

Silicone wins on two points, and both are big ones. The material gives way, which makes the same diameter more forgiving and allows a curved shape to adapt to the body. And it doesn’t break: if you drop a silicone dildo on the floor, you pick it up; if you drop a glass dildo against tile, it can be unusable in a second. It’s that trade-off that decides, and it has no general right answer—just a personal one.

No shop in our data sells the product in this market.

In this market, no shop in our data sells the item with EAN 8713221845337.

It is a remarkably consistent price picture compared with the category overall, where differences of fifty percent or more between stores are common for the same item number. The likely explanation is that the product is new in the market data—one retailer explicitly marks it as a novelty and notes "lowest price over the last 30 days" in a way that indicates no price history at all. Another retailer, in turn, lists its previous lowest price over 30 days as the same value, meaning no discount and no price movement.

Both stores were checked for pricing, which is unusual and practically significant. Still, always check the final price at checkout. Shipping is added by both stores under their respective thresholds for free shipping.

This is not a recommendation to buy from there.

Who is Toy Joy Glass Worxx Crystal Cock for—and who isn’t it for?

It’s for you who want a material that doesn’t age and doesn’t require material compromises: non-porous, with no plasticizers, compatible with all lubricants, and possible to be made completely clean. It’s for you who want to use temperature as part of the experience, because glass is one of the few materials where it actually works. And it’s for you who want a 15-centimeter insertable length in a uniformly thick shape with a clear edge under the top.

It’s not for you if you’re new at this thickness. Three centimeters in glass doesn’t give anywhere, and that’s a different thing than three centimeters in silicone. It’s not for you who want a product to use without holding it, because the ball base is a grip and not a stop base. It’s not for you who require published weight, published warranty period, and published temperature limits before buying, because Toy Joy does not publish either of these. And it’s not for you who want something that can handle being dropped.

A final observation about what the price tag actually pays for. With a battery-powered product, you’re buying a motor, a battery, and an electronic construction that all have a limited service life. Here, you’re buying a lump of glass with a molded shape. It sounds like less, but it also means that nothing in the product can stop working—it can only break. With normal care, it can be a reasonable deal, and that’s the most important reason why glass products keep selling in a category where everything else has become electronic.

Warranty, returns, and the 14-day right of withdrawal (with health- and hygiene-related exceptions for unsealed goods).

Toy Joy does not publish any manufacturer warranty with a specified duration for Crystal Cock, either on the product page or in its general terms and conditions. That’s a real difference compared to, for example, Pipedream, which states a one-year warranty on its corresponding glass item, and it should be taken into account—especially for a product where the fault, if it occurs, is typically a break in the material.

For online purchases in the EU/EEA, consumers generally have a 14-day right of withdrawal starting from when the goods are received. Under EU rules, sealed goods that aren’t suitable for return for health or hygiene reasons are exempt from the right of withdrawal once unsealed. If you buy this product in this market, the seller is also liable for defects that exist at delivery and appear within at least 2 years.

With distance purchases, EU rules generally mean the seller is liable for defects that exist at delivery and appear within at least 2 years (the legal guarantee). A defect here means an original defect in the product—an original crack in the material, a sharp molding defect, an item that doesn’t match the description—not damage you caused yourself by dropping it.

With distance selling, consumers generally have a 14-day right of withdrawal in the EU/EEA, starting 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 right to complain for defects always applies.
