These beautifully crafted ben wa balls can be used to increase the strength of the pelvic floor muscles. They also create a subtle stimulation, not meant to bring the user to an immediate orgasm, but rather to tease! Place the balls under a stream of lukewarm or cold water and the premium borosilicate material will heat up or cool down for enhanced temperature play.
