These Glass Ben Wa Balls by Topco Sales are a pretty and inexpensive way to get the strong Kegels that we all so desire. But buyer beware that these are intended as Kegel exercisers--that's it. They are made for vaginal insertion only, and designed to give your lady muscles a healthy work out to get that sexy tight feeling. So while it's a major turn-on to walk around with these babies in and no one the wiser, don't expect them to induce mind-blowing orgasms.
