## Emma's take

Smooth glass, gentle weight, a heart you feel with every move.

Borosilicate glass keeps its cool grip, and glass toys are prized for exactly that: a firm, deliberate fullness silicone can't match, with a red heart gem base doubling as your handle. This medium plug is for anyone past their first plug, ready for glass's precision instead of squish. New to backdoor play starts smaller and softer first, since glass offers zero give. Warm it under the tap or chill it in the fridge before use, and keep the base as your anchor and your stopping point.

## Frequently asked questions

## What makes this glass plug different from a silicone one?

Borosilicate glass is rigid where silicone flexes, so the pressure stays exactly where you place it. It also holds temperature far more dramatically than silicone, so a quick dip in warm or cool water changes the whole sensation.

## How do I know if the medium size fits me?

The insertable portion measures 2.44 inches long and 1.06 inches wide, a compact profile even at medium. It suits anyone who already has some plug experience and wants a firmer, more deliberate feel than their usual silicone pick.

## How do I clean and sterilize a glass plug?

Wash with warm water and mild soap after every use, and boil for a few minutes or wipe with a diluted bleach solution to fully sterilize between partners or play sessions. Glass is non-porous, so it cleans easier than most materials.

## Which lubricants are safe to use with this plug?

Any lube works here: water-based, silicone-based, or oil-based. Glass has no porous surface for lube to break down, which is one of the material's biggest advantages over TPE or jelly toys.

## Can I use temperature play with this toy?

Yes. Borosilicate glass holds heat and cold well beyond what silicone can, so a few minutes in warm water or the fridge noticeably shifts the sensation before you start.
