LELO's elegant update on the classic 'Ben wa balls' offers users longer, stronger, more attainable orgasms; reduced risk of incontinence and other pelvic floor disorders; and a faster return to tone and tightness after giving birth. They are also the only Kegel exercise system that offers you the chance to mix and match weights; each set includes two 28g and two 37g beads which can be combined in the silicone harness for a more tailored routine.
