Ben Wa Balls 2-pcs Set, Undrilled, 1.25' Diameter, Black Obsidian Gemstone, to Train and Strengthen Pelvic Floor Muscles

Get some of the most discreet sensation possible with our Black Obsidian Ben Wa Balls. This style of toy is truly ancient, with a variety of uses throughout history. Today, their main benefit, aside from pleasure, is the strengthening effect the balls can have on the pelvic muscles. Beautifully smooth, gorgeously glossy and perfectly weighted to suit most pelvic toning endeavors across the experience spectrum.

In an incomparably smooth, delightfully temperature-receptive volcanic glass that warms quickly and naturally to match body heat, the two moderately weighty spheres were designed to be held in place by the pelvic floor muscles. Because this action requires concentrated flexing and contacting of said muscles, these lovely Balls are truly perfect for helping to isolate the subtle and specific movements needed to complete a successful PC workout.
