These luxurious black Ben-Wa balls are made from borosilicate glass and designed to last a lifetime. Their size and weight make them perfect for vaginal stimulation and exercise use, and the nonporous glass is hypoallergenic and body safe. With regular use, you'll enjoy improved muscle control and stronger, more frequent orgasms.

Run them under warm water to heat things up, chill them under cold water or put them in the fridge for a cool sensation. Clean up is a snap after the fun with Pipedream toy cleaner and warm water.
