Nebula Series By Ibiza dildo in borosilicate glass 15

The Nebula Series by Ibiza dildo focuses entirely on simplicity and material quality. Made from borosilicate glass, this 18.5 cm model offers gradual penetration thanks to its tapered shape. I consider this type of product a must-have for anyone who wants to discover the sensations glass offers—density, adjustable temperature, and unmatched durability.

Borosilicate glass: why it is well suited to anal play

Borosilicate glass is not a marketing gimmick. It is a scientifically studied material designed to withstand thermal and mechanical shocks. Unlike porous materials (TPR, jelly, and some silicones), glass is completely non-porous—zero risk of bacterial retention, and cleaning with soap is sufficient. Its smooth surface facilitates insertion and creates a unique gliding sensation.

Another major advantage is temperature control. You can run it under cold water for an intense cold sensation, or warm it slightly for the opposite experience. Between you and me, this is the feature most often mentioned by my customers who switched to glass after years of using silicone.

Dimensions and safety base

This model measures 18.5 cm in total, with a diameter of 3 cm. The wide base (a crucial feature for anal play) ensures that you do not risk accidental insertion that is too deep. The weight of 226 g (transparent variant) or 220 g (pink) provides a solid feel without being heavy.

The tapered design allows for gradual insertion—particularly useful if you are new to anal penetration. Each centimeter gradually increases in diameter, making the experience more comfortable.

Transparent or pink: what is the difference?

Both Nebula Series variants offer the same dimensions and the same quality of borosilicate glass. The only difference is aesthetic:

• Transparent (18.5 cm, 226 g): classic, discreet when stored, and lets you see inside the product
• Pink (18.5 cm, 220 g): colorful, more visible, and slightly lighter (a 6 g difference, imperceptible during use)

The choice depends on your visual preferences and storage situation. Neither variant outperforms the other functionally.

Cleaning and lubricant compatibility

I recommend cleaning it with soapy water after every use. Glass tolerates mild soaps and even specialized cleaners (spray or foam). Unlike silicone, you do not risk material degradation with silicone-based lubricants—in fact, all lubricants (water-based, silicone-based, and oil-based) are compatible with glass.

When sharing, using a condom is recommended as a precaution, even though glass is less porous than other materials. After thorough cleaning, you can also put it in the dishwasher (delicate cycle) or sterilize it in boiling water.

For your first use, I recommend using plenty of water-based lubricant—the smooth glass does not create natural friction like silicone. Prepare yourself for a sensation that may be very different from what you are used to.

Who it is for and who it is not for

Ideal for: Anyone looking for an inert, durable, and easy-to-clean material. Perfect for exploring temperature play (cold/hot). An excellent entry point to anal penetration thanks to its tapered design. Also suitable for people sensitive to porous materials or phthalates.

Consider something else if: You are apprehensive about the density of glass or prefer a more “flexible” product; I suggest browsing our selection of silicone dildos, which offer more flexibility.

Advice from a friend— Borosilicate glass often seems intimidating before use. Once you take the plunge, many customers never go back. Take your time, use plenty of lubricant, and savor the unique sensation that only glass can offer.
