This remarkable anal plug is made of glass which makes it perfect for temperature play! It also warms up to body temperature quickly and can be used together with any kind of lubricant. The anal plug has a surprising glow-in-the-dark effect. Expose the plug 2 minutes to bright light or bright it 30 seconds with a flashlight. The anal plug has a wide, flat base which makes it safe to use the plug. Clean the anal plug after use with lukewarm water and a mild antibacterial soap or toy cleaner.
