Nebula Series By Ibiza anal plug in clear borosilicate glass

If you're the kind of person looking for a reliable and versatile anal accessory, this borosilicate glass plug checks all the boxes. I've seen hundreds of them come through the store, and the feedback is consistent: durability, a smooth sensation, and easy cleaning. Borosilicate glass isn't a trend; it's a technical choice that makes a difference.

Borosilicate glass: why this material?

Borosilicate glass is a nonporous material, meaning it retains neither bacteria nor odors after cleaning. Unlike silicone or TPE, it won't gradually deteriorate. It resists thermal shock (you can run it under hot or cold water without worry), and its smooth surface offers a unique sensation—different from silicone, with a more mineral feel. I consider this type of product a long-term investment: you buy it once, and it stays with you for years.

Dimensions and insertion comfort

With a total length of 11 cm and a base diameter of 5 cm, this plug offers a moderate size suitable for most users. The wide base (5 cm) ensures safety and prevents accidental insertion that is too deep. The weight (approximately 306 g) provides a noticeable sensation without being aggressive. For beginners exploring anal play, it's a good starting point. For more experienced users, it's a reliable everyday accessory.

Handcrafted design and two shades to choose from

Each piece is handmade, adding a touch of authenticity. You’ll find two versions: transparent (classic and discreet) and pink (more aesthetic for some). Although the weight and dimensions are nearly identical between the two, the pink shade may have a slight visual impact depending on your preferences. Honestly, the choice between them mainly comes down to your mood—the performance is equivalent.

Simplified use and care

Before first use, rinse it with lukewarm water and mild soap. After each use, I recommend thorough cleaning (soapy water followed by a generous rinse). The glass is not affected by temperature changes, so you can also sterilize it in boiling water if you wish. Compatible with all lubricants (water-based, silicone-based, and mineral oil—the glass absorbs nothing). If sharing with a partner, using a condom remains the best hygiene practice.

• Nonporous material: easy to clean, no deterioration

Who it’s for—and who it isn’t

Who it’s for: Beginners exploring anal play who want a reliable, durable product. Experienced users who appreciate a mineral feel. Couples looking for a versatile, easy-to-clean accessory. Anyone who prefers to invest once in a product that lasts.

Who it isn’t for: If you’re looking for vibrating or pulsing stimulation, this passive plug won’t be right for you—consider our selection of electronic sex toys instead. If you want a more compact product for maximum discretion, the 5 cm diameter may feel a little large.

A friend’s advice— Borosilicate glass can seem intimidating at first, but it’s a material that never disappoints. Once you’ve tried it, you understand why luxury boutiques have been using it for years.
