Nebula Series By Ibiza model 5 anal plug in clear borosilicate glass

This Nebula Series anal plug focuses on simplicity and high-quality materials. Borosilicate glass is the smart choice for anyone seeking gradual, safe anal penetration. Unlike silicone, glass heats up or cools down quickly—you can run it under hot or cold water before use to vary the sensations. This is something my customers often ask me: “Does it really make a difference?” Yes, absolutely.

Borosilicate glass: why it’s a smart choice

Borosilicate glass isn’t ordinary glass. Its chemical composition (boron instead of calcium) makes it highly resistant to thermal shock and impacts. You can drop it on a tiled floor without it breaking—that’s why it’s used in laboratories and professional kitchens. For a sex toy, this means exceptional durability, zero porosity (so no bacteria can settle in it), and easy cleaning with soapy water. I consider this material one of the most hygienic on the market, on par with medical-grade silicone.

Another advantage: glass doesn’t deteriorate over time. No discoloration, no chemical odor developing with age. It’s a long-term investment—you can keep it for years.

Dimensions and size: compact anal plug

At 12.5 cm in total length and 3.5 cm in diameter, this is an accessible size. Not huge, not tiny. The wide base (a crucial element for anal safety) prevents the toy from slipping too far inside. This is something I’ve seen hundreds of times in the shop: an insufficient base means panic and discomfort. Here, that issue is solved.

This size is suitable for people discovering anal exploration and looking for something gradual. The weight (220 g in transparent and 232 g in pink) provides a noticeable presence without feeling heavy.

Transparent vs. pink: two looks for the same product

The only real difference between the two variants is the appearance and color of the material. Transparent = classic and timeless. Pink = visually softer, while remaining the same borosilicate glass. There is no difference in sensation or performance. Choose according to your personal preference or your desire for discretion (transparent = less noticeable in the shower or when stored).

Use and lubricant compatibility

Before first use, wash it with hot water and mild soap. Glass absorbs nothing, so you don’t need talc or any special treatment. After each use, follow the same process: water + soap, then dry it.

When it comes to lubricant, you have complete freedom of choice: water-, silicone-, or oil-based. Glass is compatible with all of them. If you share the toy, use a condom (a universal recommendation for any shared sex toy, regardless of the material). Browse our sex toy cleaners for optimal care.

Who it’s for and who it’s not for

Who it’s for: People discovering anal exploration and looking for a gradual size. Those who enjoy temperature play (hot/cold water). Anyone who wants a durable, timeless toy without complicated maintenance. Those who appreciate a clear aesthetic and the absence of electronics.

Who it’s not for: If you’re looking for vibration or movement, this isn’t the product for you—borosilicate glass is passive by nature. If you prefer a larger or more discreet size, check out our dildo collection for other dimensions. If you have a phobia of glass (even highly resistant glass), choose a silicone alternative.

Friendly advice — Borosilicate glass requires a little extra care when stored (avoid direct impacts on corners), but it’s worth it. It’s an object you can keep for a long time, enjoy looking at, and that never disappoints when it comes to sensation.
