Pipedream Icicles No. 79 borosilicate glass anal plug N.

This borosilicate glass plug is a classic that never goes out of style. I consider this type of product a must-have for anal play: a premium material, unique sensations, and, honestly, it can last a lifetime if you take good care of it. Glass allows for temperature play that no other material can offer—you can warm it under hot water or cool it in the freezer to vary the sensations. That is what really makes the difference for those looking to explore beyond simple penetration.

Borosilicate glass and effortless care

Borosilicate glass is THE benchmark material for durable sex toys. Non-porous, hygienic, and chemically inert—it does not absorb bacteria or degrade over time. Unlike porous materials (TPE, TPR, jelly), you do not systematically need to use a condom, and cleaning is genuinely effortless. Use lukewarm water and mild soap, or put it straight in the dishwasher if you prefer maximum convenience. I think it is a smart investment: you buy it once and keep it for years.

Temperature play is the bonus of glass. Soak it for 2–3 minutes in very hot water (not boiling) for a soothing, enveloping sensation, or put it in the freezer for 15–20 minutes for an invigorating coolness. This thermal capacity creates sensations you will not find anywhere else—it is often what makes people switch to glass after trying silicone.

Compact dimensions, ideal size for beginners

With 7.3 cm of insertable length and a 3 cm diameter, this plug is clearly designed for beginners or gentle exploration. It is not oversized; it is a learning tool—you can really take your time and feel how your body responds without being overwhelmed by its size. The weight (168 g) feels substantial without being heavy. I recommend this size to anyone discovering anal play or looking for a discreet companion for regular sessions without intense physical demands.

• Insertable length: 7.3 cm (compact, accessible)
• Diameter: 3 cm (gradual, non-intimidating)
• Material: borosilicate glass (durable, temperature-responsive, hygienic)
• Weight: 168 g (substantial, stable)
• Handcrafted (each piece is unique)

Use and compatibility

Before the first use, I recommend cleaning it with lukewarm water and mild soap, then running it through the dishwasher if possible—this ensures maximum hygiene. When it comes to lubricant, you have options: water-based (compatible with everything), silicone-based (be careful with silicone-on-silicone if you have other toys), or even oil-based if you want to try it. With glass, there are no material compatibility concerns—you can really use whatever suits you.

During use, the glass naturally warms through contact with the body. To enhance the sensation, soak it in hot water just beforehand. Afterward, clean it simply with lukewarm water, then store it somewhere dry. No lingering odors and no degradation—that is why I consider glass one of the best long-term investments. If you want to explore durable-material alternatives, glass is clearly a must-try.

Who it is for and who it is not for

Who it is for: Beginners in anal play who want a safe, durable material. People looking for unique temperature sensations. Those who share regularly and prioritize maximum hygiene. Practitioners who invest in equipment that lasts for years. Fans of gradual sensations without electronics.

Who it is not for: If you are looking for vibration or multiple modes, passive glass cannot provide that—choose an electronic plug or a vibrating dildo instead. If you have a fear of glass or the sound of glass (even minimal), this is not for you. If you want a very large size for extreme play, this format is too compact.

Advice from a friend— Glass is a little like wine: it gets better with time and proper care. Invest in it once, and you will have a reliable companion for years. And temperature play? Honestly, once you have tried it, you understand why glass has remained popular for decades without being replaced.
