Toy Joy Glass Worxx Crystal Heart Anal Dildo: review

Glass Worxx Crystal Heart Anal Dildo in brief — here’s what you get

Crystal Heart Anal Dildo is a glass dildo from Toy Joys’ Glass Worxx series. It has no motor, no battery, no app, and no modes. The entire product is one single piece of borosilicate glass: five smooth, gradually growing beads on a shaft, and at the bottom a wide heart-shaped handle that serves as both a grip area and a stop. This means the assessment looks completely different from that of a vibrator — there is no run time to compare, no charging time, and no noise level. What remains is the material, dimensions, shape, and how well the manufacturer documents its product.

The manufacturer states that the material is high-quality borosilicate glass and describes the series as hypoallergenic, body-safe, and intended for temperature play. If the dimensions tell you one thing according to the manufacturer’s own product graphic: insertable length 11.5 centimeters. Total length is not shown on the manufacturer’s site — it comes from the stores, which all state 15 centimeters and a maximum diameter of 3 centimeters. In Sweden, the item is sold by four stores for 329 or 359 SEK, and all four had it in stock at the price check on September 12, 2026.

This review covers the item with EAN 8713221845351, the manufacturer’s article number 10622-CLEAR. The number has been verified in the page source on Toy Joys’ own product page. Worth knowing before you compare stores: the article number contains the word CLEAR, but the manufacturer’s own product images show a rose-toned glass product, and Blush Me lists the color as Rosa, while Vuxenkul lists both Rosa and Transparent in its color field. It’s the same EAN across all four stores, so the price comparison holds — but the color designation in the store’s range tree is not something to rely on.

What borosilicate glass is, and why it’s used here

Borosilicate glass is the type of glass used for laboratory glassware, coffee pots, and baking dishes. What sets it apart from regular lime-soda glass is the added borosilicate, and this is most noticeable in how little the material moves when the temperature changes. The ISO 3585 standard defines the quality of borosilicate glass 3.3 and sets the average linear thermal expansion coefficient to 3.3 ± 0.1 × 10⁻⁶ per kelvin in the range 20 to 300 degrees, the density at 20 degrees to 2.23 ± 0.02 grams per cubic centimeter, and the average thermal conductivity between 20 and 200 degrees to 1.2 watts per meter and kelvin.

What this means in practice is two things. The first is that the material can withstand temperature changes without cracking in the way that ordinary glass does—low thermal expansion means small stresses in the material when one side becomes warm before the other. That is the entire technical basis for why glass products in this category are marketed for temperature play. The second is that the thermal conductivity of 1.2 watts per meter and kelvin is low for a solid material but several times higher than silicone’s, which is why glass feels cool against the skin for longer than a silicone object with the same temperature.

There is, however, one clarification worth making. Toy Joy writes "borosilicate glass" but does not state any quality, any standard, or any glass composition. The figures from ISO 3585 apply to borosilicate glass 3.3 as a material class, not as a commitment about exactly this product. Instead, the manufacturer’s packaging bears the labeling SAFETY GLASS, which is a marketing term without a defined meaning—there is no published testing behind it.

Crystal Heart, Crystal Cock, or Dual-Ended—what is which for Glass Worxx?

Glass Worxx is a whole series, and three of the models are so close in price that they get mixed up in the store listings. The manufacturer’s own product graphics make the difference clear because each one states its insertable length.

• Crystal Heart Anal Dildo — the model this text is about. Bulb-shaped shaft, heart-shaped handle, insertable length 11.5 cm, 33.99 euros from the manufacturer.
• Crystal Cock — realistically shaped glass dildo with a wide base, insertable length 15 cm, the same price of 33.99 euros. EAN 8713221845337.
• Dual-Ended Anal & G-spot Dildo — double-sided, with a curved G-spot end that is 10 cm insertable and a ball-shaped studded anal end that is 8 cm insertable, 31.99 euros. EAN 8713221845344.

So the difference is not quality or material — all three are stated to be borosilicate glass and have the same five markings — but rather the shape and how deeply they are intended to go. If you want the most insertable length for the money, the Crystal Cock model is the one; it offers 15 centimeters versus Crystal Hearts 11.5 for the exact same price from the manufacturer. If you want two different types of stimulation in the same object, Dual-Ended is the cheapest of the three.

Material and build quality: one-piece glass

The material issue is the only characteristic of an intimate product that can’t be compensated for through experience or care, and on a product without electronics it is practically the entire evaluation. Toy Joy specifies a single material for Crystal Heart: high-quality borosilicate glass. There are no other components, no seam, no glued joint, no cap, and no charging port. What can be concluded is that a product without joints has nowhere for residue to get stuck.

Why the pore-free material is the whole point

Glass is a pore-free material. A pore-free surface can be cleaned, because there are no microscopic cavities where residue can stay. It is the single most important property of a material that is meant to lie against mucous membrane, and it is especially important in anal areas, where bacteria and residue are a completely different matter than in vaginal areas. The manufacturer labels the product EASY TO CLEAN and HYPOALLERGENIC, and states that it is cleaned with warm water and mild soap or sex toy cleaner.

Glass also differs from silicone in one point that is rarely mentioned: it doesn’t age. Silicone absorbs fat and perfume over time, turns yellow, and becomes tacky on the surface when exposed to the wrong lubricants, and softened plastics like TPE and PVC break down faster than that. A glass object looks the same after ten years as the day it came out of the box, provided it hasn’t been hit. That is the real difference between glass and everything else in this category, and it is also the reason why the price of 329 SEK should be considered over a significantly longer period of use than a silicone product in the same price range.

The downside lies in the same property. Glass is brittle. It can’t be bent, it doesn’t withstand impacts, and when it breaks it does so suddenly and with sharp edges. The manufacturer’s manual addresses exactly that: the product must be inspected before every use and may not be used if it is damaged, cracked, deformed, or has sharp edges, and it must not be bent, twisted, or exposed to force. This is not a formality on a glass product — it is the level of control that replaces all the maintenance that a silicone product requires.

Phthalates, plasticizers, and why glass avoids the whole issue

Phthalates are a group of plasticizers 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. Just intimate products are a recurring subject of oversight because the category contains a lot of soft plastic against the skin and mucous membranes.

Glass requires no plasticizers at all. It is not a polymer, it contains no additives that can migrate into the body, and the question of which phthalates are included therefore makes no sense. It is the strongest material argument a product in this category can have, and at the same time it is what makes the “hypoallergenic” label on the packaging reasonable rather than marketing: there is nothing in pure glass to react to.

The comparison with cheaper anal products is therefore ruthless. A product labeled “TPE” or “jelly rubber” says nothing at all about which plasticizers are included, and a product with silicone only on the outer shell often has a hard plastic core with a seam where the two materials meet. Crystal Heart has no seam, no outer-shell material, and no core. There is one material, and it is that material that you come into contact with.

Measurements: 11.5 centimeters insertable, 15 centimeters total, and 3 centimeters maximum.

The size description requires a clarification because the manufacturer and the shops do not publish the same information. Toy Joy publishes a single measurement: insertable length 11.5 centimeters, and it is not stated in the text on the product page, but in the manufacturer’s own product graphic in the image gallery. Total length, diameter, and weight are entirely missing from the manufacturer.

The shops fill in the gap. Vuxen lists total length 15 centimeters, insertable length 11.5 centimeters, and diameter 3 centimeters. Blush Me lists exactly the same three measurements with two decimal places. Vuxenkul lists length 15 centimeters and diameter 3 centimeters but writes penetration depth 11 centimeters, i.e., half a centimeter less than the others. Where two details differ, the manufacturer wins, and the manufacturer’s own graphic indicates 11.5. Vuxenkul’s 11 centimeters should therefore be read as a rounding in the shop’s article data, not as another variant.

What the three numbers mean together is worth pausing on. The total length of 15 centimeters minus the insertable length of 11.5 centimeters gives 3.5 centimeters, which are the handle and tip. That is a significant portion of the product, and it’s exactly what you want on something intended for anal use. The diameter of 3 centimeters applies to the widest ball; the balls gradually grow from the tip, which the manufacturer describes as letting you build up the sensation step by step. A maximum circumference is not published by either the manufacturer or any of the four stores, which is the piece of information that otherwise says the most about how a product with this kind of shape is actually experienced in terms of size.

The weight nobody publishes

Neither Toy Joy nor any of the four Swedish stores publishes a weight for Crystal Heart. The manufacturer’s product data in the web shop has a weight field, but it’s left blank. This is a real shortcoming for this exact type of product, because weight is one of the properties that makes glass differ most from everything else: a massive glass object weighs many times more than a silicone object of the same size, and the heaviness is part of how the product behaves.

The density for borosilicate glass 3.3 is 2.23 grams per cubic centimeter according to ISO 3585, so the figure could be estimated if the volume were published. It isn’t either. What can therefore only be established is this: the product is solid glass all the way through, and it then weighs accordingly—but no one publishes how much. Assume that it is noticeably heavier than a silicone dildo in the same format, and treat every weight specification you see in another compilation as uncertain until the manufacturer reports it.

Shape: five balls and a heart-shaped handle

Without a motor, settings, and buttons, the shape is the entire interface. The manufacturer describes it in two sentences: smooth, rounded balls that let you build up the sensation step by step, and an elegant heart-shaped handle that provides both comfort and control in every movement. That’s also all that’s stated—Toy Joy does not specify either the number of balls, their individual diameters, or the distance between them. What you can count from the manufacturer’s own product images is five balls on the shaft, increasing in size from the tip up toward the handle.

What the heart-shaped handle does—and why the base matters for anal use

The handle isn’t decoration. For an anal product, the base is the single most important safety detail, and Toy Joy’s own manual states the rule plainly: products intended for anal use are designed with a wide base and may only be used as intended. The reason is that the rectum pulls inward and that an object without enough base can slip in beyond reach—that is the most common acute cause connected to this product category, and the only one that is a real medical problem rather than just discomfort.

The heart shape solves it in two ways at the same time. It’s wider than the thickest ball, which makes it a physical stop, and it’s flat enough to be gripped between your fingers even when it’s wet. What sets a heart-shaped handle apart from a round disc is that the heart’s two lobes give your fingers something to brace against in two directions. On a glass product—which is slippery when it’s wet and must not be dropped—grip isn’t a comfort issue; it’s a durability issue.

The handle is also the part that determines whether the product can be used alone or with a partner. A firm grip 3.5 centimeters outside the body gives full control over both depth and pace, and unlike a vibrator there’s no control to find by feel. Vuxenkul describes the control option as "None / Hand-controlled", which is a correct and unusually straightforward wording.

How the five balls build up the sensation step by step

The idea behind a ball-shaped shaft is that each ball provides a clear in-and-out passage, rather than the smooth gliding a smooth rod gives. The manufacturer puts it as the balls invite you to build up the sensation step by step. Between the balls there are grooves, and it’s these that keep the product in place between movements instead of letting it glide back.

The practical consequence of the balls growing is that the size is adjustable without you changing the product. If you stop at the third ball, you use a narrower product than the specified diameter of 3 centimeters; if you go all the way to the handle, you use the full 11.5 centimeters and the widest ball. It’s the same logic that makes anal balls a common beginner product, except that everything here sits on a rigid shaft and can therefore be controlled precisely.

The counterargument is just as simple: glass doesn’t give. A silicone dildo with the same diameter compresses a bit and follows the body’s angle, while a glass dildo does neither. That makes 3 centimeters in glass something different than 3 centimeters in silicone, and it’s the most important reason why this model isn’t an obvious first purchase for anal play. The manufacturer states that the product shouldn’t be exposed to force; in use, that means it’s the lubricant and your patience that are supposed to do the work, not the pressure.

Temperature play: what the manufacturer promises and what the manual forbids

Temperature play is the function Toy Joy markets most aggressively. The product page says the glass can be warmed for a sensual feel or cooled for a tingly experience, the packaging carries the TEMPERATURE PLAY symbol, and the same symbol appears in the manufacturer’s product graphics. The material choice is, as I said, logical: low thermal expansion means the glass can handle temperature differences that would shatter ordinary glass.

But here there is a contradiction in the manufacturer’s own material that no store mentions. Toy Joy’s general user manual explicitly states that the product must not be heated, frozen, or exposed to temperatures above 45 degrees. So the product page sells a function that the manual forbids in plain text. The manual is titled "Motorised Intimate Products" and is written for battery-powered products, which is the likely explanation — but Toy Joy does not publish a separate manual for Glass Worxx or for any other glass product. Their manual page contains the general manual plus two product-specific manuals for pumps and rechargeable products, and none of them applies to this series.

What this means in practice is that the buyer is left without manufacturer instructions for the function sold on the packaging. The only thing that is actually documented by Toy Joy about how temperature play is supposed to be done is the wording on the product page: warm for sensual enjoyment or cool for a tingly experience. There is no specified temperature, no specified method, and no specified time. The safe advice therefore becomes conservative — use lukewarm and cool tap water respectively, check the temperature against the inside of the wrist before contact with the mucous membrane, and stay well away from boiling water, a microwave oven, a freezer, and a dishwasher regardless of how the glass is marketed.

Lubricant: the product page says it all; the manual says water

The second contradiction in the manufacturer’s material concerns lubricants, and it matters more than the first one seems to. The product page for Crystal Heart states that the product is compatible with all types of lubricants. That is correct from a materials-technology standpoint: glass is chemically inert; it is not broken down by silicone-based lubricants the way silicone products do, and it does not absorb oil the way softened plastics do. On a clean glass product, the lubricant issue is, in practice, solved.

Toy Joy’s general manual says something else: use only water-based lubricant, because oil- and silicone-based lubricants can damage certain product materials. The wording "certain product materials" reveals that this is a general rule written for an entire range, not a message about glass. Where the manufacturer’s product-specific instruction and the general manual clash, the product page carries more weight for this article, but it is the reader who has to make that assessment — Toy Joy does not.

There is, however, a practical caveat that applies regardless of the material. Silicone-based lubricants are harder to rinse off and leave a film that makes the product slicker for longer than you’d expect, which on a massive glass object is a real risk of slipping. Water-based lubricant is rinsed off right away with tap water and is therefore the simple choice here — not for the sake of the material, but for grip.

Cleaning, storage, and the inspection before each use

Cleaning is the part where a product without electronics wins the most. Toy Joy states that Crystal Heart is cleaned with warm water and mild soap or a sex toy cleaner, and the manual specifies the routine: clean before and after each use, rinse thoroughly, and let the product dry completely before putting it away. There is no button to avoid, no charging port to keep dry, and no seam to poke at. The entire object can be held under running water and wiped dry at once.

Water resistance: no IP rating is published

Toy Joy does not publish an IP rating for Crystal Heart. There is no IPX number on the product page, none in the product graphic, and none on the packaging image. The manual points to the packaging and adds a rule worth reading carefully: products without a specified water-resistance rating must not be exposed to water.

That rule is clearly written for electrical products and conflicts with the manufacturer’s own cleaning instructions for this specific item, which assumes warm water. On a massive glass object without electronics, there is nothing that water can damage, and that is the reasonable interpretation. But it should be said plainly that the manufacturer does not say so. The only one actually making a claim is the retailer Vuxenkul (the retailer), which states "Vattentålig: Ja" (Water-resistant: Yes) in its specification — a store statement, not a manufacturer statement, and without any classification behind it.

Storage, on the other hand, is well documented. The manual specifies dry, dust-free, and clean storage, avoiding direct sunlight, heat, and moisture, and — the most important point here — that products should be stored separately from each other to avoid reactions between different materials. A bag or a separate storage box is recommended. No storage bag is stated as included in the delivery; Toy Joy publishes nothing about the contents of the delivery for this item at all, and none of the four shops does either. For a glass product, this is a real shortcoming, because a bag is what protects against exactly the kind of impact that can make the product unusable.

The inspection required by the manufacturer before each use

This is the only routine that truly sets glass apart from other materials, and it is taken verbatim from Toy Joy’s manual. Inspect the product before each use. Do not use it if it is damaged, cracked, deformed, or has sharp edges. Do not bend, twist, or stretch the product, and do not expose it to force. Do not use it on irritated, inflamed, or damaged skin. Do not share intimate products without appropriate hygienic protection.

On a massive glass item, the inspection comes down to two things you can do in five seconds. Hold the product up to the light and look for hairline cracks, especially in the transition between the handle and the shaft, where the glass is at its thinnest. Then run your finger over the entire surface and feel for chips. A crack that doesn’t show up in backlighting practically doesn’t exist, and a surface that feels smooth with your finger is smooth. If the product has been dropped on a hard floor, it should be discarded even if it looks intact—that’s the only reasonable rule for glass against mucous membrane.

The manual also covers a point that rarely shows up in store descriptions: anyone who is pregnant, has recently had surgery, or has an implanted medical device should consult a doctor before use. Toy Joy also explicitly states that the product is sold as an adult item and is not intended for medical or therapeutic use—a wording that’s easy to overlook but relevant if you were considering the product as a dilation aid.

Crystal Heart compared with the alternatives

Three comparisons are relevant: against the two sister models in the same series, which have identical material and the same price point but a different shape, and against another brand’s glass assortment. All details below come from each manufacturer’s own published specifications.

Against Glass Worxx Crystal Cock — 3.5 centimeters more insertable, same price

Crystal Cock costs 33.99 euro from the manufacturer, i.e. exactly the same as Crystal Heart, and has EAN 8713221845337. The manufacturer’s product graphics indicate an insertable length of 15 centimeters—3.5 centimeters more than Crystal Heart’s 11.5. The material is the same, the markings are the same, and the shape is realistic rather than ball-shaped, with a wide flat base foot instead of a heart-shaped handle.

The choice between them therefore isn’t about money but about two things. The first is depth: if you want a longer insertable length, Crystal Cock is the only one of the three that reaches beyond 11.5 centimeters. The second is whether you want an even surface or a ball-shaped shaft—a smooth realistic shape gives continuous gliding, while the balls create a marked passage per ball. Someone who’s unsure about anal will generally do better to choose the shorter product with the clearer base, i.e. Crystal Heart. Retailer Vuxen lists Crystal Cock at 329 SEK, i.e. the same Swedish price as Crystal Heart when it’s at its cheapest.

Against Glass Worxx Dual-Ended Anal & G-spot Dildo — two products in one

Dual-Ended Anal & G-spot Dildo costs 31.99 euro from the manufacturer, i.e. two euro less, and has EAN 8713221845344. The manufacturer’s graphics indicate two insertable lengths for the same product: 10 centimeters on the curved G-spot end and 8 centimeters on the ball-tipped anal end. In the middle of the shaft sits a wide collar that works as a stop for both openings.

The advantage is obvious: you get two shapes for less money than one. The drawbacks are two, and both are concrete. One is that the anal end only offers 8 centimeters of insertable length, compared with Crystal Hearts 11.5—that’s 30 percent less. The other is hygiene: a double-sided product that’s used both anally and vaginally requires thorough cleaning between the ends, and the middle collar that forms the base is not as wide as a heart-shaped handle. If you want a dedicated anal product with a clearly defined base, Crystal Heart is the better design; if you want the widest range of use for the least money, Dual-Ended is the one.

Against Pipedream Icicles — same material, different documentation

The second big glass assortment in Swedish stores is Pipedream’s Icicles. The comparison is instructive precisely because the two manufacturers publish different things. On Pipedream’s own product page for Icicles No. 62, the material is described as glass, hypoallergenic, porous-free, and body-safe, and the manufacturer explicitly states a one-year manufacturer’s warranty. The price is $53.99. However, Pipedream does not publish total length, insertable length, diameter, or weight on that page.

Toy Joy does the opposite: it publishes a measurement—the insertable length of 11.5 centimeters—but provides no warranty period at all beyond the fact that the statutory one applies. Neither manufacturer publishes weight. It says something about the category as a whole: glass products are sold based on material and appearance, and the level of specification is far below what the same stores require of a vibrator in the same price range.

For the buyer, the conclusion is practical. If you already have an Icicles and are wondering whether Glass Worxx is something else, the answer is that the material category is the same and that the difference lies in shape, price, and which details you get to read before purchase. The price favors Toy Joy in Sweden: 329 SEK for Crystal Heart is low for a solid glass product with a published insertable length.

Price range: 329 to 359 SEK, and four stores have stock

Four Swedish stores sell the item with EAN 8713221845351. Vuxen, Blush Me, and SexleksakerOutlet are all at 329 SEK, while Vuxenkul is at 359 SEK. The difference between the cheapest and the most expensive is 30 SEK, or a little over nine percent—one of the tightest price ranges in our entire material, and a clear contrast to the vibrator category, where the same item often differs by several hundred kronor between stores.

All four stores had the product in stock at the price check on September 12, 2026. That means the price comparison is actually something you can act on—unlike situations where the cheapest store is sold out and the price shown in the feed is never payable. Three stores at the same lowest price also means you can choose based on shipping terms and delivery time instead of on kronor.

A note about the shops’ descriptions belongs here. The manufacturer states that Crystal Heart was developed for anal pleasure, and the product name on the packaging is CRYSTAL HEART ANAL DILDO. The adult market is promoting it at the same time with the point “For both vaginal and anal use.” It’s not wrong in terms of facts — the shape does not prevent vaginal use, and the wide handle makes it safe in both cases — but it’s a shop formulation and not something the manufacturer writes. If you go by the manufacturer’s own description, this is an anal product first.

The prices in the table above are updated when the shops’ product feeds are updated, but always check the final price at checkout. In this price range, all four shops are below the threshold for free shipping, which means that the shipping cost is a larger share of the total price than the price difference between the shops — a 30 SEK price difference is easily eaten up by 29 SEK in shipping at the wrong shop.

Who is Crystal Heart for — and who is it not for?

It’s for you if you want a material without a best-before date. Glass doesn’t age, it doesn’t absorb fat or perfume, it doesn’t require any softeners, and it can be made completely clean every time. It’s for you if you want an anal product with a base that is actually wide, and if you want to be able to control the size based on how deep you go rather than by buying several products. It’s for you if you’re curious about temperature play, because it’s a feature that no silicone item can deliver. And it’s for you if you want to avoid charging cables, apps, and batteries that get used up after three years.

It’s not for you if you want a forgiving material. Glass doesn’t give, and 3 centimeters in glass is perceived as more than 3 centimeters in silicone. It’s not for you if you want vibration — there is no motor and there won’t be one. It’s not for you if you’re rough with your things or if you store them loosely in a drawer together with other items, because a chip makes the product unusable. And it’s not for you if you require complete specifications before purchase: the manufacturer publishes neither total length, weight, circumference, what’s included in the delivery, IP rating, nor warranty period.

One more thing belongs in the decision. There is no product-specific manual for this item. Toy Joy’s manuals page contains a general safety instruction for motorized intimate products, as well as two manuals for other product types, and the general instruction contradicts the product page in two points — temperature and lubricant. It doesn’t affect the glass in your hand, but it does affect how much guidance you actually get with the product, and it’s a reasonable objection to a manufacturer that, in other respects, labels its packaging with five different feature icons.

Warranty, complaints, and right of withdrawal

Toy Joy does not provide its own warranty period for the Crystal Heart. The manual states that the product is covered by the applicable statutory warranty, that it covers material and manufacturing defects during normal use, and that normal wear and tear, accidents, incorrect use, lack of maintenance, and its own modifications are not covered. Proof of purchase is required. So it is not a manufacturer warranty in the strict sense, but a reference to what the law already gives you—worth noting since Pipedream in the same category states a one-year warranty and Satisfyer in the neighboring category states a fifteen-year warranty.

The manufacturer of the product is TOYJOY, Bijsterhuizen 3151, 6604 LV Wijchen in the Netherlands, and TOYJOY® is stated to be a registered trademark and company name belonging to SCALA 2.0 B.V. It’s worth keeping in mind if you ever need to make a complaint with the shop—but in practice it is the shop you bought from that is your counterparty.

If you buy directly from the manufacturer, their own terms of purchase also apply: a fourteen-day right of withdrawal, return within 30 days after you have notified that you are withdrawing, reporting of visible defects within 48 hours from delivery, and hidden defects within two months. The terms also expressly state that products with a broken hygiene seal cannot be returned. The 48-hour rule is short and worth knowing—unpack and inspect the product on the same day it arrives.

If you shop at any of the four Swedish stores, Swedish consumer law applies, and it is stronger. Under konsumentköplagen, you have three years of right to complain about defects in the goods, regardless of what the manufacturer does or does not promise. For distance purchases, you also have a right of withdrawal within fourteen days under lagen om distansavtal och avtal utanför affärslokaler. Be aware that in practice the right of withdrawal is limited for hygienic items that have been taken out of a sealed package—but the right to complain about defects always applies. If you have questions about what applies in your case, Konsumentverket guides you via Hallå konsument.
