## Emma's take

Clear, weighty, and made to be felt.

Glass does something silicone never manages: it holds cold or heat exactly where you place it, and the weight of the Biird Anii settles in with a presence that builds slowly, filling without rushing. Reviewers reach for it when they want unhurried wear, not a quick session. The flared base is clean and secure, borosilicate is sterilizable, and the clarity of the piece is genuinely striking. Best suited for anyone ready to move past soft beginners' plugs and into something with real weight and temperature range.

## Frequently asked questions

## What makes borosilicate glass safe for anal play?

Borosilicate glass is non-porous, hypoallergenic, and completely body-safe. It won't harbor bacteria, doesn't degrade with cleaning, and can be fully sterilized by boiling between uses.

## How do I use the Biird Anii for temperature play?

Rest the plug in a bowl of warm water for a few minutes to warm it, or refrigerate briefly for a cool sensation. Always test the temperature against your inner wrist before use. The glass holds its temperature well once applied.

## Is the Biird Anii beginner-friendly?

It suits someone who has some experience with anal play and wants to explore temperature and weight rather than someone trying a plug for the very first time. The firm, unforgiving material rewards a little preparation and plenty of lube.

## What lube works best with a glass plug?

Water-based lube is a reliable choice and works with every toy material. Silicone-based lube is also compatible with glass if you prefer a longer-lasting formula. Avoid anything oil-based if latex condoms are also in play.

## How do I clean and store the Biird Anii?

Wash with warm water and mild soap after each use. For full sterilization, boil for two to three minutes or run it through the top rack of a dishwasher without detergent. Store wrapped in soft cloth to protect the surface from nicks.
