Review on 💎 Black Obsidian Gemstone Ben-Wa Balls Set - Undrilled, 2-pcs for Pelvic Floor Muscle Strengthening and Training (30MM) by Stephanie Johnson

This product is a complete waste of money. Health and Household? More like health and wallet drain. Through trial and error, I found that this gemstone did absolutely nothing to help strengthen my muscles. The un-drilled design makes it difficult to use as a massage tool, and the size of the stone is too small for any real muscle coverage. Save your money and invest in a real massage tool instead.
