Nebula Series By Ibiza dildo in transparent borosilicate glass 18

The Nebula Series by Ibiza anal dildo is a borosilicate glass classic for good reason: this material offers a rare combination of strength, sensation, and practicality. I consider this product a must-have for anyone who wants to discover glass without any hassle.

Borosilicate glass: why it matters

Borosilicate glass isn’t a marketing choice—it’s chemistry. This type of glass contains boron instead of calcium, giving it exceptional thermal resistance and making it far less fragile than ordinary glass. For a sex toy, that means you can run it under hot water without worry, cool it in the fridge for a different sensation, and it won’t crack at the slightest impact. It’s also non-porous—no bacteria can take up residence in it—and easy to clean with soapy water. Between you and me, that’s why I often recommend it to beginners who are hesitating between silicone and glass.

Dimensions and size: an accessible model

With a total length of 18.5 cm and a diameter of 3.5 cm, this dildo is a medium-sized model, neither too imposing nor too discreet. The wide base, a characteristic of the Nebula series, ensures maximum safety—it prevents overly deep insertion and makes handling easier. The weight of 306 g for the clear version or 296 g for the pink version gives it a pleasant presence without tiring the pelvic floor muscles during prolonged use. This size suits both people who are just discovering anal play and those looking for something more substantial than small beginner dildos.

Two finishes for two preferences

The product comes in two distinct variants: clear and pink. The clear version offers a clean aesthetic and lets you see the light passing through the glass—a detail many people appreciate. The pink version adds a touch of color while retaining the same quality and dimensions. There is no difference in sensation or performance between the two—it’s simply a matter of visual preference and personal taste.

Care and compatibility

I find that one of the great advantages of glass is how easy it is to care for. After each use, a quick wash with soapy water is enough. You can also sterilize it in boiling water if you wish, unlike silicone, which does not tolerate very high temperatures well. Glass is compatible with all lubricants—water-based, silicone-based, and oil-based—with no restrictions. If you share it, use a condom as you would with any sex toy. Store it in a dry place, ideally in the supplied bag or pouch, to prevent impacts.

Who it’s for, and who it isn’t

Who it’s for: People who want to explore anal play without electronics, are looking for a durable and easy-to-maintain material, or are hesitating between silicone and glass. This dildo also suits people who enjoy temperature sensations—cooling or warming the glass before use creates a unique sensory experience. Couples considering pegging also appreciate this type of dildo for its strength and ease of handling.

Who it isn’t for: If you’re worried about the fragility of glass or are looking for something more compact and discreet, I’d point you instead toward our silicone dildos, which offer flexibility and lightness that glass does not. If you want vibration, you’ll also need to look elsewhere—borosilicate glass cannot be electronic.

Friendly advice— Here’s what I think based on customer feedback and the technical specifications: this dildo is a great choice for anyone who wants something solid and durable. The sensation of glass is genuinely different from silicone—smoother and more “slippery”—and many people enjoy it. Don’t get discouraged if your first attempt feels awkward; like anything else, anal play takes some getting used to. Take a look at our beginner’s sex toy guide if you’re truly just starting out.
