Nebula Series by Ibiza borosilicate glass anal plug

This Nebula Series anal plug focuses on simplicity and material quality. Borosilicate glass is a smart choice for anyone looking for a durable, hygienic sex toy. Unlike porous synthetic materials, glass does not retain bacteria, is easy to clean with soap and water, and its smooth surface makes it pleasant to hold.

Borosilicate glass material: why it matters

Borosilicate glass is not just a “luxury” material—it is a genuine technical feature. This glass resists impacts and temperature variations without breaking or deforming. In practical terms, this means you can run it under cold water and then warm water without any risk. Its natural smoothness and ability to adapt to your body temperature make it a unique object for exploring sensations. In my view, glass is an investment: you buy it once, and it lasts for years.

• Non-porous — no retention of bacteria or odors
• Simple soap cleaning — no talc or specialized spray required
• Thermal — adapts to body temperature or can be cooled/warmed before use
• Transparent or pink — two aesthetic options to suit visual preferences
• Wide safety base — prevents overly deep insertion

Dimensions and size: for starting out or progressing

At 10.5 cm in total length and 3 cm in diameter, this model is an entry-level option. It is a reassuring size for anyone new to anal penetration. The wide base, a Nebula feature, provides extra safety and makes handling easier. Its weight (134–136 g depending on the color) makes it easy to hold and position without causing fatigue.

Two variations: transparent or pink

The color choice is not merely cosmetic—it reflects your aesthetic preferences. The transparent version offers a direct view of the material and its smooth texture, while the pink version adds a bolder visual touch. Both are made from identical borosilicate glass and have the same dimensions and properties. Choose the one that appeals to you.

Lubricant and compatibility

With glass, you have the luxury of being able to use any lubricant: water-based (recommended for beginners), silicone-based (if you prefer longer-lasting lubrication), or even oil-based. There is no chemical reaction or material degradation. This is a real advantage compared with synthetic materials, which impose restrictions. I recommend a lubricant designed for sex toys if you are a beginner—it is easier to measure and control.

Who it is for and who it is not for

Who it is for: Beginners in anal penetration looking for a reassuring size. People seeking a hygienic, durable material. Those who enjoy exploring temperature sensations (cooling or warming it before use). Fans of streamlined design without electronics or complications.

Who it is not for: If you are looking for active stimulation (vibration, pulsing), passive glass will not meet your needs. Instead, check out our sex toys with stimulation or a larger option. If you are concerned about materials feeling “cold” at first, start with silicone, which better matches body heat from the moment of contact.

A friend’s advice — Borosilicate glass is a smart long-term purchase. It does not degrade, so you do not need to replace it every year. Invest in a good water-based lubricant for your first use, take your time, and you will discover why so many people return to glass once they have tried it.
