Gold Ben Wa Balls - Pleasure Balls

The Gold Ball Keigal Muscle Marbles are two independent metallic spheres intended for insertion and retention within the vagina. Insert one or both of these balls and squeeze and retain them using the famed Keigal muscles. Over time you will find that the stronger your Keigal muscles become the better grip they can have on penises, vibrators and just about anything else they come into contact with.
