Gildo Glass Dildo No. 4: review

Gildo’s handmade glass dildo reviewed against the manufacturer’s own specifications and pricing data from four Swedish shops. Total length 17,5 centimeters, thickest point 3,5 centimeters, 16 centimeters insertable, and 473 grams flawless glass with a flat base—plus three points where the shops say the manufacturer is wrong.

My rating

A handmade glass dildo where the whole point is the material: non-porous, tough against all lubricants, and possible to both chill and warm. The manufacturer states a total length of 17.5 centimeters and 3.5 centimeters as the maximum diameter, and the shops fill in 16 centimeters insertable and 473 grams. The flat base makes it safe for anal use, and the curved shaft is directed toward the front wall. What you pay for is the weight, the total absence of give, and documentation that lacks both the type of glass and a consumer warranty.

  • Total length 17.5 cm and max diameter 3.5 cm according to the manufacturer’s size chart
  • Insertable length 16 cm and weight 473 g according to retailers
  • Non-porous glass — tolerates all lubricants, even silicone-based
  • Flat base, as stated by the manufacturer as safe for anal penetration
  • No battery, no motor, nothing that stops working
  • 249–399 SEK at four stores for the same EAN

Gildo Glass Dildo No. 4 at a glance — this is what you get

Gildo Glass Dildo No. 4 is a handmade glass dildo without a motor, battery, or electronics. The entire product is a single piece of transparent glass with blue spirals enclosed in the material, a lightly curved shaft, and a flat, flared base. The manufacturer is ONE-DC, the Dutch company that owns the Gildo brand, and the manufacturer’s own product description already includes the measurement: Gildo - Glass Dildo No. 4 - 17,5 cm. The item number is GIL527CLR.

The specification looks like this. Total length 17.5 centimeters and maximum diameter 3.5 centimeters according to the manufacturer’s own measurement chart. Insertable length 16 centimeters and minimum diameter 2.7 centimeters — these two details come from the retailers Vuxen and Lekosmek, not from the manufacturer. The material is listed as glass. The base is flat. The shaft is slightly bent, which the manufacturer directly links to stimulation of the prostate or the G-spot. In Sweden, the item is sold by four retailers at prices between 249 and 399 SEK, and two of them had it in stock at the price check on July 29, 2026.

This review is about the item with EAN 8719497660261. The number is verified directly against the manufacturer: the EAN-Barcode field on ONE-DC’s product page for GIL527CLR shows that exact number, and the same number is used by the Danish retailer Peech for the same model. That matters here, because Gildo numbers its glass models sequentially — No. 1, No. 4, No. 5, No. 15, No. 19, No. 20, No. 29, and so on — and each number has its own EAN, which differs in the last three digits. Two models can therefore look almost identical in a retailer feed and still be completely different products.

A note about the name before we move on. The manufacturer writes the brand as Gildo, in the singular. The Swedish retailer Vuxen lists the same item under the brand name "Gildos" and the product name "Glasdildo No. 4", while Blush Me and Lustly use the manufacturer’s English name. It’s the same item number and the same EAN for all three — just different spelling in the retailer’s own catalog.

What a glass dildo is, and how it differs from silicone

A glass dildo differs from a silicone product in four points, all of which are consequences of the material rather than the construction. The first is hardness. Glass does not yield at all. Adult lists elasticity as “Not bendable” and stiffness as “Hard,” which is a store claim but also an obvious consequence of the product being made of glass. That means the pressure from the tip is not distributed over a yieldable surface the way a silicone product does; instead, it concentrates exactly where the glass is in contact.

The second is weight. The retailers Lekosmek and Peech both list 473 grams—that is a store claim; the manufacturer does not publish any weight. Put that figure into context: Fun Factory states 236 grams for its largest Limba Flex in silicone, which is a little longer (18.1 centimeters) and significantly thicker (4.1 centimeters in diameter). The glass dildo therefore weighs about twice as much as a larger silicone product. Heaviness is a trait you either look for or want to avoid, but it is not up for negotiation.

The third is heat conductivity. Glass conducts heat far better than silicone and can therefore be both cooled and warmed to a temperature you can feel. The manufacturer explicitly describes temperature in its Gildo texts: a few minutes in the refrigerator or under warm or cold water is enough. That is the only “function” the product has, and it costs nothing in battery life.

The fourth is that the glass is non-porous. The manufacturer describes the glass as a strong and hygienic material that feels smooth, and it’s that characteristic that allows the product to be used with any lube—including silicone-based lube, which destroys silicone products over time. It’s a real and underrated practical advantage.

What you don’t get is just as important to list. No motor, no vibrations, no modes, no app, no battery, no charging cable, and no IP rating to take into account. There is nothing that can stop charging, nothing whose capacity decreases with the number of charging cycles, and no electronics that determine the product’s service life. That is why the specification table further down contains so many rows that are blank on an electric product.

No. 4, No. 1, or No. 20— which Gildo is which?

The Gildo series consists of about twenty glass models that shops often mix up, because they have the same brand, the same material description, and almost identical description texts. Three of them are close enough to No. 4 to be worth distinguishing.

  • Glass Dildo No. 4 — the model this text is about. 17.5 centimeters, blue spirals inside the body, a slightly bent shaft, a shaped head, and a flat base. EAN 8719497660261.
  • Glass Dildo No. 1 — also 17.5 centimeters, but with blue ridges on the outside of the shaft and yellow bands on the glans. The manufacturer explicitly states that the ridges provide extra stimulation when the dildo is moved up and down. A structured surface, then, while No. 4 is smooth. EAN 8719497660186.
  • Glass Dildo No. 20 — 23 centimeters with a bulb-shaped shaft, a narrow tip, and a wide base. A completely different product: longer, with a shape that’s built on repeating balls rather than an even shaft. EAN 8719497660254.
  • Realistic Glass Dildo No. 29 — 18 centimeters with a veined shaft and a rounded top, the manufacturer’s realistic glass model. EAN 8719934017764.

The difference between No. 4 and No. 1 is therefore not the length—both are 17.5 centimeters—but whether you want a smooth surface or a ridged one. What makes No. 4 special in the series is the combination of a smooth surface, a bent shaft, and a shaped head that’s broader than the shaft. If you want structure against the vaginal wall, No. 1 is the logical model; if you want a longer product with balls, it’s No. 20.

Material and build quality: glass all the way through

The material issue is the only characteristic of an intimate product that can’t be compensated for with experience or care. It determines whether the product is still hygienic after five years. Here’s an unusually simple answer: the manufacturer specifies a single material, and that material is glass. There’s no seam, no glue joint, no shaft made of another plastic, and no soft tip sitting on a hard base. The product is one piece.

Why pore-free material matters

A non-porous material lacks microscopic cavities where residue and bacteria can remain after cleaning. It’s the single most important property of a material that should lie against mucous membranes, and glass is in practice the least porous surface available in this product category. The manufacturer puts it like this: glass is strong, hygienic, and feels smooth. Pipedream says the same thing about its own glass series Icicles—in other words, the glass is hypoallergenic, non-porous, and safe for the body.

Compare it with the other end of the category. Kemikalieinspektionen describes phthalates as a group of plasticizers used to make plastic—especially softened PVC—flexible, and several of them can affect the endocrine system and make reproduction more difficult. Material labels like "TPE" or "jelly rubber" don’t say anything about which plasticizers are included. Glass doesn’t need any plasticizers at all to become glass. The question of phthalates simply doesn’t arise, and it’s a stronger message than almost every promise a manufacturer can write. The retailer Vuxen also lists the product as "Kroppssäker & Fri från Ftalater".

The impact in everyday life is that the product can be cleaned thoroughly and does not age chemically. A silicone product can become sticky or porous from the wrong lubricant; a TPE product can “sweat” softeners. Glass does neither. What can happen to glass is mechanical—and we cover that in the durability section.

Borosilicate glass or regular glass—what the manufacturer actually says

Here there’s a gap in the documentation that’s worth being clear about. The manufacturer only states “glass” and never specifies which type of glass it is. Neither the product page, the product name, the dimension diagram, nor the packaging image mentions borosilicate glass.

Two retailers do the opposite, though. Lustly calls the product “Glasbladsdildo i Borosilikatglas” in the page title, and the Danish retailer Peech explicitly writes borosilicate glass as body-safe and describes it as significantly more durable than regular glass. Both are store claims. They don’t contradict the manufacturer, but they go further than what the manufacturer itself writes—and you should know about that difference before you buy based on that particular feature.

Why does the type of glass matter? Borosilicate glass has a lower coefficient of thermal expansion than regular lime-soda glass, which in plain terms means it can withstand faster temperature changes without cracking. That’s the whole reason why laboratory glassware and oven dishes are made from borosilicate. For a product marketed around temperature feel, this isn’t a detail—it’s the core of whether the function is safe to use aggressively. What can be stated is that the manufacturer itself never promises borosilicate, and the manufacturer’s own temperature guidance is also cautious: a few minutes in the fridge, or hot and cold water. Not boiling water, not the freezer, not the microwave.

Measurements and weight: 17.5 cm, 16 cm insertable, and 473 grams

The manufacturer’s own dimension diagram for the article is unusually useful. It shows the product against a centimeter scale with a lipstick as a size reference, and it gives two values in plain text: Length: 17.5 cm and Max. Ø: 3.5 cm. The same 17.5 centimeters also appears in the product name. So there are two separate places from the manufacturer that provide the same length.

Two details that the manufacturer does not publish are filled in by the retailers. Vuxen gives an insertable length of 16 centimeters and a minimum diameter of 2.7 centimeters, and Lekosmek gives the same insertion depth of 16 centimeters as well as the diameter range of 2.7–3.7 centimeters. The difference between 17.5 and 16 centimeters is the base and the flared rim, which should not be inserted. So it’s about 1.5 centimeters that stays outside the body.

The diameter is where the figures split. The manufacturer states a maximum of 3.5 centimeters on its own measurement chart. Vuxen and Lekosmek both list 3.7 centimeters as the maximum diameter. Blush Me and Peech write 3.5 centimeters, so the same as the manufacturer. Two millimeters sounds like a little, but at this measurement it’s about a six percent difference in circumference, and for anyone who’s right on the borderline in thickness, it’s relevant. When the manufacturer and the store disagree, the manufacturer’s figures apply: count on 3.5 centimeters at the thickest point, which is the head.

The weight is not published by the manufacturer. The retailers Lekosmek and Peech both list 473 grams, and the fact that two independent stores land on exactly the same number suggests they pull it from the same supplier data. Treat the figure as a store claim, but a well-substantiated one. Practically, just under half a kilo means two things: the product sits firmly and doesn’t need to be pressed, and it can’t tolerate being dropped on a tiled floor.

The shape is worth its own line. The shaft is evenly thick and smooth, with the spiral pattern enclosed in the material—so the pattern isn’t on the surface and doesn’t feel like texture. The head is shaped and wider than the shaft, which is what creates the clear transition at insertion. The base is a flared, round plate. Vuxen describes the base type as "Smooth" and the texture as "Smooth", which matches the manufacturer’s own product images.

That’s how you use the Gildo Glass Dildo No. 4

There are no buttons, no modes, and no learning curve in the interface. The entire use comes down to three things: how the base is handled, how the curved shaft is positioned, and how temperature is used. The manufacturer’s own description is short, but it includes all three—flat base for safe anal penetration, curved shaft for the prostate or G-spot, and temperature play through a refrigerator or water.

The flat base—and why it’s crucial for anal use

The manufacturer states plainly that the flat base is what makes the dildo safe to use for anal penetration. The wording isn’t marketing; it’s a technical prerequisite. The rectum lacks the natural stopping function that the sleeve has, and an object without a flared base can therefore be pulled in farther than intended. This is the most common cause of emergency visits related to this product category, and the only design detail that prevents it is precisely a base that’s wider than the shaft.

On No. 4, the base is a round, flared glass disc. It serves two functions at the same time: it acts as a stopping foot, and it provides grip. Because the glass is hard and smooth — and becomes more slippery with lubricant — the base is what you hold, not the shaft. An adult describes the base type as smooth, which means it is not suction-cup shaped. So it doesn’t attach to tile or a shower wall, and the product is not intended for hands-free use or for sitting in a harness.

The manufacturer also brings up a hygiene point that few store texts reproduce. In its care instructions for ONE-DC’s Gildo-series glass products, it points out that if the dildo is used both anally and vaginally, the surface must be cleaned very carefully with lukewarm water and a toy cleaner in between, to minimize the risk of harmful bacteria. This is the single most important instruction in the entire text, and it applies no matter how porous the material is: porous means the surface can be cleaned, not that it cleans itself.

Bent shaft for G-spot and prostate — what the bend does

The manufacturer states that the slightly bent shaft makes it possible to stimulate the prostate or the G-spot. The mechanics behind it are simple: both the prostate and the area usually called the G-spot are against the front wall, a couple of centimeters in. A straight rod points straight forward and passes by; a bent rod directs the tip upward toward the front wall and keeps it there when the shaft is twisted.

What makes the construction effective specifically for this model is the combination of the bend and a head that is wider than the shaft. The transition between the head and the shaft creates a clear edge, and it is the edge — not the tip — that does most when the rod is drawn back. Also, the shaft being completely unbendable means the force is transferred directly from the hand to the tip without anything flexing. A silicone product with a bendable core, like Fun Factory’s Limba Flex, works the other way around: it adapts to the body instead of the body adapting to it.

Practically speaking, that means the glass requires a steadier hand. With 473 grams and no give, there’s no margin for pushing. The movement should come from the wrist, in short changes of angle, and all force should be deliberate. That’s also why this kind of product is less suited for fast, hard movements than a soft silicone dildo — and better suited for slow, targeted pressure on a specific area.

Temperature play: how to heat and cool the glass safely

Temperature play is the only “function” the product has, and it’s also the only one where you can get it wrong. The manufacturer’s own instructions for Gildo-series glass products are measured and should be followed word for word: put the product in the refrigerator for a few minutes, or hold it under warm or cold water for a few minutes. The retailer Lekosmek describes the product as “heat- and cold-resistant,” and Lustly and Blush Me highlight temperature play as one of the main selling points.

Note what the manufacturer does not specify. Nowhere in this series are freezing, boiling water, a microwave, or a dishwasher mentioned. Other manufacturers of glass products list more methods, but those are their products and their glass — and since Gildo never specifies the type of glass, there’s no reason to assume the model can handle more than the manufacturer itself states.

The practical advice that follows from material science is to avoid rapid changes. A glass that has just been in the refrigerator shouldn’t be held under hot water, and vice versa. It’s the temperature difference over a short time that cracks glass, not the absolute temperature. Always check the temperature against the inside of your wrist before using the product — mucous membrane can tolerate less than the palm, and the glass keeps its temperature significantly longer than silicone would.

Cleaning, lube, and storage

Care is easier than on almost any other product in the category, precisely because there’s no electronics that need to be kept dry. The manufacturer states in its product description that the dildo should be cleaned before and after use for safe and hygienic use, and in the care text for the same series it says that the cleaning is done with lukewarm water and toy cleaner. The retailer Vuxen lists the product as “Waterproof: Yes,” which, for a solid glass item with no openings, is an obvious feature rather than a specification.

Which lube works with glass?

All of them. This isn’t a simplification; it’s the manufacturer’s own wording: the dildo can be used in combination with any type of lube. Both Blush Me, Lustly, and Lekosmek repeat the same thing.

It’s a real advantage that’s easy to overlook. On a silicone product, silicone-based lube is out of the question, because it breaks down the surface over time and makes it porous — and a porous surface can’t be cleaned properly anymore; it only can be replaced. Glass has no such limitation. In addition, silicone-based lube lasts significantly longer than water-based without drying out, which matters for a product that’s firm and has no give. If you want maximum glide, this is one of the few products where you can freely choose.

A couple of practical notes, though. Oil-based products like coconut oil are not harmful to the glass, but they leave a film that has to be washed off thoroughly, and they break down latex condoms if such are used. And regardless of lubricant, the manufacturer’s cleaning instructions apply both before and after—the glass doesn’t get clean just by quickly rinsing it.

Storage and how to avoid damaging the glass

The manufacturer’s care text for the Gildo-series glass products states that the included storage pouch protects the dildo from dust and scratches. The retailer Lustly also writes that an elegant and discreet storage pouch is included in the delivery. It’s a store-specific detail for this particular item — the manufacturer’s product page for No. 4 does not list any delivery contents at all — but it matches how the manufacturer describes the series otherwise.

The point of the pouch isn’t dust prevention, but scratch prevention. A scratch in the glass surface isn’t just cosmetic: it creates a stress concentration that makes the glass weaker exactly at that spot, and it also creates an edge where residue can get stuck on a surface that would otherwise be completely smooth. So store the product separately from other items, not loosely in a drawer together with metal or other hard toys. That’s the only care effort the product actually requires.

Durability: what can actually break

On an electric product, the battery is what sets the limit for its service life. Here, there’s no battery, no motor, no charging contact, and no seal that ages. Pipedream puts it for its own glass series by saying that, with proper care, the product is designed to last for life. That’s reasonable: glass doesn’t age chemically, it doesn’t fade, it doesn’t get sticky, and it doesn’t lose rigidity.

What can break instead is mechanical, and there are three realistic scenarios. The first is falling against a hard surface—473 grams of glass against a tiled floor ends badly. The second is impact against other glass or against a faucet, for example when cleaning the sink basin. The third is thermal shock, meaning a temperature change that’s too fast.

All three can be prevented, but they deserve to be stated plainly, because a cracked or chipped glass product must not be used again under any circumstances. Check the surface against the light before every use and feel along the entire shaft, head, and base rim with your finger. If you find a chip, a scratch that you can feel with your fingernail, or a crack, the product should be discarded. It’s a simple routine, and it’s the only safety routine a glass product requires.

The opposite is also true: a glass product that’s cared for properly has no predetermined point when it will be used up. That’s the single most important difference compared to every battery-powered product in this price range, and it should be factored in when comparing the price against a cheaper vibrator that’s used up when the cell is used up.

Gildo Glass Dildo No. 4 compared with the alternatives

Four comparisons are relevant: against the two closest models in the same series, against the most well-known competing glass brand, and against silicone as a material choice. All the information below comes from the respective manufacturer’s own specifications, and it is marked there where it instead comes from a shop.

Against Gildo Glass Dildo No. 1 — smooth surface or ribbed?

No. 1 is exactly the same length: 17.5 centimeters according to the manufacturer’s product name, the same as No. 4. It is also transparent glass with blue inside, and it has a flat base for both anal and vaginal use. The difference is entirely in the surface. The manufacturer describes No. 1 as transparent with blue ridges on the shaft and yellow bands on the tip, and it explicitly states that the ridges provide extra stimulation when the dildo is moved up and down.

No. 4 instead has the spirals enclosed in the body material. The pattern can be seen but not felt—the shaft is smooth, which Vuxen also states in its texture description. So these are two different products for two different preferences, not a better and a worse one. If you want a feeling of texture against the vaginal wall with every movement, you choose No. 1. If you want the least possible friction and maximum glide—which is especially relevant for anal—you choose No. 4. The manufacturer publishes neither the diameter nor the weight for No. 1, so on those two points, the models cannot be compared using manufacturer data.

Against Gildo Glass Dildo No. 20 — 5.5 centimeters longer

No. 20 is the series’ long model: 23 centimeters according to the manufacturer’s product name, i.e. 5.5 centimeters longer than No. 4. The shape is also different. The manufacturer describes a ball-shaped shaft with a narrow tip and a wide lower part, while No. 4 has an evenly thick shaft with a shaped head. With balls, you get a series of distinct transitions instead of one; with No. 4, you get an edge at the head and then a smooth glide.

About No. 20, the manufacturer writes that the glass is heavier than typical dildos and that it can be cooled or warmed under the tap for a few minutes—the same temperature argument as for No. 4. That a 23-centimeter-long glass rod weighs more than a 17.5-centimeter-long one follows from the geometry, but the manufacturer does not publish any weight for No. 20, so the difference cannot be quantified. If you choose based on length, the decision is simple. If you choose based on control and handling, most of the arguments favor the shorter model.

Against Pipedream Icicles No. 8 — the same material, different documentation

Icicles is the most widespread competing glass brand in Swedish shops, and Pipedream’s description of the material is close to Gildo’s: hand-blown glass that is hypoallergenic, non-porous, and body-safe, and which, according to the manufacturer, is designed to last a lifetime with proper care.

Two differences are worth mentioning. The first is the warranty. Pipedream states a one-year manufacturer warranty on Icicles No. 8, while ONE-DC does not publish any consumer warranty at all on its product page for Gildo No. 4 — the company runs a wholesale portal, and the page contains no warranty terms aimed at end customers. This makes Pipedream the better choice for someone who places importance on a stated manufacturer warranty, with the caveat that a warranty on a glass item in practice only covers manufacturing defects.

The second is the size documentation, and that’s where Gildo wins. Pipedream’s product page for Icicles No. 8 does not publish either length, diameter, or weight in running text — the measurements are listed in fields that are not shown on the page. Gildo, on the other hand, provides both length and maximum diameter in its own measurement graphic with a scale. For anyone comparing numbers before buying, that’s a noticeable practical difference, and one of the few times a wholesale page is more informative than a consumer page.

Against Fun Factory Limba Flex — glass against silicone

The most illuminating comparison is not against another glass product but against silicone. Fun Factory lists three sizes for Limba Flex: S at 12 centimeters and 3 centimeters in diameter at 111 grams, M at 18 centimeters and 3.2 centimeters at 169 grams, and L at 18.1 centimeters and 4.1 centimeters at 236 grams. The material is described as body-safe, non-porous, and hypoallergenic, and the model has a bendable core.

Put Limba Flex M next to Gildo No. 4. The silicone product is half a centimeter longer (18 vs 17.5 centimeters), slightly narrower (3.2 vs 3.5 centimeters), and weighs 169 grams compared with the 473 grams the stores state for the glass dildo. It’s almost three times as heavy, with practically the same outer dimensions. That’s where the entire difference in experience lies: the silicone gives way and follows the body, while the glass doesn’t and instead sits firmly on its own weight.

Both materials are non-porous and both are hypoallergenic according to their respective manufacturers, so they’re equal when it comes to hygiene. The differences that actually matter are three: the glass tolerates all lubricants while silicone does not tolerate silicone-based, glass can be heated and cooled while silicone barely holds temperature, and silicone is bendable while glass is not. If you choose based on flexibility and ease, Limba Flex wins. If you choose based on weight, targeted pressure, temperature play, and freedom to choose lubricants, Gildo No. 4 wins.

Price range: 249 to 399 SEK and two stores with stock

Four Swedish stores sell the item with EAN 8719497660261. Cheapest is Blush Me at 249 SEK, most expensive is Lekosmek at 399 SEK. That’s a difference of 150 SEK, or 60 percent, for the same item number and the same packaging. In between are Lustly at 262 SEK and Vuxen at 349 SEK.

The inventory situation is at least as important as the price spread. Only two of the four shops had the product in stock during the price check: Blush Me at 249 SEK and Vuxen at 349 SEK. Lustly and Lekosmek were sold out. This means the difference between the cheapest and the second-cheapest available option in practice was 100 SEK, not 150. Shops that list a product as sold out may still have an old price in the feed, and that price is rarely what you actually end up paying when the item comes back in.

The price spread is not because any shop sells a different variant. All four shops list the item under the manufacturer’s article number GIL527CLR or under their own number, which is tied to that particular model. So it is about the shops’ own margin setting for a product that lacks a recommended price in Sweden. In this price range, shipping costs are also often decisive: several shops offer free shipping only above 799 SEK, which can eat up the entire price difference if you buy just one item. Always check the final price at checkout.

Conflicting information between the sources—and what applies

Three contradictions appeared when all four shop pages and the manufacturer’s material were read against each other. They are presented here in full, because they affect what you can actually count on.

  • Length: 17.5 or 18 centimeters? Vuxen’s bullet list at the top of the product page states “Length 18 cm,” while the shop’s own quick spec table further down on the same page states a total length of 17.5 centimeters. The manufacturer lists 17.5 centimeters in two places—in the product description and on the dimension drawing. Count on 17.5 centimeters.
  • Maximum diameter: 3.5 or 3.7 centimeters? The manufacturer’s dimension drawing shows 3.5 centimeters. Vuxen and Lekosmek both state 3.7 centimeters as the maximum diameter, while Blush Me and Peech state 3.5 centimeters. The manufacturer’s value applies: 3.5 centimeters.
  • Glass type: borosilicate or unspecified glass? Lustly and Peech write borosilicate glass. The manufacturer only writes “glass” and never specifies the type. Treat borosilicate as a shop claim and follow the manufacturer’s restrained temperature instructions regardless.

In addition to these three, there are two details that no manufacturer source covers at all: the weight of 473 grams, which comes from Lekosmek and Peech, and the storage pouch, which Lustly states for this specific item, while the manufacturer only mentions a pouch in its care text for the sister model No. 29. Both are likely correct, but both are shop claims.

Who is the Gildo Glass Dildo No. 4 for—and who is it not for?

It fits you if you want weight and firmness rather than flexibility. At 473 grams and with a completely unbendable shaft, the product provides a targeted, controllable pressure that a soft silicone dildo can’t replicate, and the curved shaft with the wider head is designed specifically for thrusting at the front wall. It’s for you who want to be able to use any lube you like, including silicone-based lube, and for you who want temperature to be a real variable rather than a marketing gimmick.

It also fits you if you prioritize hygiene over features. A massive glass item with no seams, seals, motor housing, or charging contact is the simplest product there is to clean, and the only one that can reasonably last for decades. The measurements are also restrained—16 centimeters insertable and 3.5 centimeters at its thickest—which makes it a reasonable first glass product rather than a specialty model.

It doesn’t fit you if you want vibration or something that moves on its own; there’s no motor, and there will never be one. It doesn’t fit you if you prefer soft, yielding material—there, Fun Factory Limba Flex is the obvious opposite. It doesn’t fit you if you want a product that adheres to the wall, since the base is smooth and isn’t a suction cup, and it doesn’t fit you in a harness. It also doesn’t fit you if you want an explicit manufacturer warranty on paper, because ONE-DC does not publish any for end customers.

And one more thing belongs in the decision: it doesn’t fit you if you’re not careful with your things. A glass product requires a single routine—check the surface against the light before each use and store it so it doesn’t rub against other items—but that routine isn’t optional. If you can’t imagine keeping it, you should buy silicone instead.

Warranty, complaints, and right of withdrawal

The manufacturer does not publish any consumer warranty for Gildo Glass Dildo No. 4. ONE-DC runs a wholesale portal aimed at retailers, and the product page for GIL527CLR contains no warranty terms for the end customer. That’s in itself not unusual for a product without electronics, but it means you have no optional manufacturer warranty to lean on—unlike Pipedream, which states a one-year warranty for its corresponding glass model.

What always applies instead is your statutory rights, and they’re stronger than most people think. Under konsumentköplagen, you have three years to make a complaint if the item is faulty, regardless of what the manufacturer promises or does not promise. A manufacturing defect in the glass—an internal stress that makes the product crack during normal use, a sharp edge that hasn’t been sanded down—is a fault in the item, and it’s the shop you make the complaint to that matters, not the manufacturer.

For distance purchases, you also have the right of withdrawal for fourteen days under the law on distance contracts and contracts outside business premises. Be aware that, in practice, the right of withdrawal is limited for hygiene items that have been removed from a sealed package — and this product is delivered in a hanging package, which counts as exactly such a seal. The right to complain about defects applies, however, always, whether the package has been opened or not. If you have questions about what applies in your case, Konsumentverket guides you via Hallå konsument.

Common questions about Gildo Glass Dildo No. 4

How long and thick is Gildo Glass Dildo No. 4?
The manufacturer states the total length as 17.5 centimeters and the maximum diameter as 3.5 centimeters in its own measurement chart, and the same length is also given in the product name. The retailers Vuxen and Lekosmek provide two details that the manufacturer does not publish: insertable length 16 centimeters and minimum diameter 2.7 centimeters. Note that the same two stores list 3.7 centimeters as the maximum diameter, i.e., two millimeters more than the manufacturer. In that case, the manufacturer’s information applies. Vuxen’s bullet list also states a length of 18 centimeters, while the store’s own quick-facts table on the same page states 17.5 centimeters—and there too, the manufacturer’s 17.5 centimeters is what applies.
Is Gildo Glass Dildo No. 4 safe to use anally?
The manufacturer explicitly states that the flat base makes the dildo safe to use for anal penetration. It is the crucial design detail: the rectum lacks the natural stop function that the slide has, and a flared base that is wider than the shaft is the only thing that prevents the object from being pulled in further than intended. The base also works as a grip, which is practical since the glass becomes slippery from lubricants. The manufacturer also points out that the surface must be cleaned very carefully with lukewarm water and toy cleaner if the product is used both anally and vaginally, to minimize the risk of harmful bacteria.
Which lubricant works with a glass dildo?
All types. The manufacturer states that the dildo can be used in combination with any type of lubricant, and all Swedish stores repeat that. It’s a real advantage compared with silicone products, where silicone-based lubricants break down the surface over time and make it porous. Silicone-based lubricants also last longer without drying out, which is relevant for a product that is completely hard and has no give. Oil-based products such as coconut oil do not damage the glass but leave a film that must be washed off thoroughly, and they break down latex condoms.
Can you heat or cool the Gildo Glass Dildo No. 4?
Yes, and it’s the product’s only real function. For the Gildo series’ glass products, the manufacturer states that the glass can be heated or cooled by leaving it for a few minutes in the refrigerator or under warm and cold water, respectively. Retailer Lekosmek describes the product as heat- and cold-resistant. Note what the manufacturer does not specify: neither freezer, boiling water, microwave, nor dishwasher is mentioned for this series. Avoid rapid switching—it’s the temperature difference over a short time that cracks the glass. Always check the temperature against your wrist before use, since glass retains its temperature significantly longer than silicone.
Is it made of borosilicate glass?
The manufacturer never specifies the type of glass. Neither the product page, the size guide, nor the packaging image mentions borosilicate—it only says “glass.” Two retailers go further: Lustly calls the product borosilicate glass in the page title, and the Danish store Peech writes body-safe borosilicate glass, described as tougher than regular glass. Both are store claims. The difference matters because borosilicate has a lower thermal expansion and therefore tolerates faster temperature changes. Since the manufacturer never promises borosilicate, you should stick to the manufacturer’s own, moderate temperature instructions.
What’s the difference between Gildo No. 4 and Gildo No. 1?
Not the length—both are stated by the manufacturer as 17.5 centimeters. The difference lies in the surface. No. 1 is transparent with blue flutes on the outside of the shaft and yellow stripes on the glans, and the manufacturer expressly writes that the flutes provide extra stimulation when the dildo is moved up and down. No. 4 has the spirals enclosed inside the body, which means the pattern is visible but not felt; Vuxen describes the texture as smooth. If you want structure against the vaginal wall, you choose No. 1; if you want the least possible friction, you choose No. 4. The manufacturer publishes neither the diameter nor the weight for No. 1, so on those points they can’t be compared using manufacturer data.
How much does it weigh, and why does weight matter?
Both retailers Lekosmek and Peech list 473 grams. The manufacturer does not publish a weight, so the figure is a store listing—but the fact that two independent stores state exactly the same number suggests that it comes from the same supplier data. Weight is the most noticeable difference compared to silicone: Fun Factory lists 169 grams for Limba Flex M, which is 18 centimeters long and 3.2 centimeters in diameter, meaning almost the same external dimensions. The glass dildo weighs about three times as much. Practically, that means the product sits firmly and provides targeted pressure without needing to press—but it also means it can’t handle being dropped.
Which warranty applies, and what happens if the glass breaks?
The manufacturer does not publish any consumer warranty for this product. ONE-DC runs a wholesale portal aimed at retailers, and the product page contains no warranty terms for end customers—unlike Pipedream, which states a one-year warranty on its corresponding glass model Icicles No. 8. What you always have are your statutory rights: three years’ right to complain about defects in the goods under konsumentköplagen, which you assert against the store, and a fourteen-day right of withdrawal for distance purchases. The right of withdrawal is, in practice, limited for hygiene products that have been removed from a sealed package. A product that has chipped or cracked must never be used again, no matter how small the damage looks.

I run the site myself and have reviewed 395 products since 2023. Before that, I worked for eight years as a buyer of intimate hygiene products, and that’s where the product knowledge comes from. Each review is based on the manufacturer’s own specifications, product data sheets, and price data from all the shops that sell the product — all sources are at the very bottom of the page and can be checked. I compare the models against each other based on what can actually be verified: materials, dimensions, intensity levels, water-resistance rating, warranty, and price. If you find an error, I want to know about it.
