Simple, yet stylish - these elegant Ben-Wa balls are handcrafted from borosilicate glass and designed to last a lifetime. Their size and weight make them ideal for both vaginal stimulation and exercise use and the nonporous glass is hypoallergenic and body-safe.

If these crystal balls are used regularly, you will enjoy improved pelvic muscle control and more frequent mind-blowing orgasms. Harmony Tip: Run them under warm water to heat things up, or pop them in the freezer for a chilling effect.
