An extra long, ultra shiny, simply and pleasurably functional take on the classic pelvic floor strengthener, the Ben Wa Balls on a String from Nasstoys combine a weighty, kegel strengthening design with an arousing feel. 

Each of four weighted balls is perfectly spherical with a super sleek ABS plastic body; they're perfectly shaped to fit comfortably and pleasurably, sitting precisely in place for maximum muscle strengthening. The weights inside jiggle and jump with movement, creating a naturally vibrating effect that feels amazing while toning muscles responsible for orgasm and sexual control. A sturdy string holds the balls together in the middle, a long tail as a withdrawal cord. 

In slick, non porous plastic, clean-up is easy using warm soapy water or a good toy care fluid/foam. Compatible with all lube types.

* The Balls are 16.5" (41.9cm) in total, 13" (33cm) insertable, each is 1.35" (3.4cm) in diameter
