If you’ve ever heard of Ben-wa balls, you have a pretty good idea of what the Smart Balls are. These little things are great for excercising your vaginal muscles, and they also have the metal balls inside. Every time you move, the balls inside will shift and move, giving you a quite pleasant sensation that’s almost entirely unlike anything you’ve experienced before.

They are also good for quiet stimulation. You literally cannot hear these Smartballs doing their magic, but oh they will do their magic quite thoroughly.
