Combining elegance and sensuality, these marble-sized ben wa balls are crafted in solid hand-blown glass and feature delicate purple butterflies in the center of each. The duo comes nestled in a white satin-lined heart shaped tin, perfect for safe and discreet storage when the label is removed. A great way to tone vaginal muscles and intensify orgasmic pleasure, crystal balls can be used on their own or in tandem with a Kegelmaster routine.
