Review on Enhance Wellness with ACU-Balls Chinese Health Medicine Marble Baoding Stress Balls: Ideal for Stone Massage Therapy and Hand Exercise, Comes with Stand by Ryan Hare

Whoever sells them has a damn pair of stones. Unlike the cheaper ones you can buy in Chinatown for $5, these are very good quality - hard, heavy and smooth as eggs. Since they're marbled, they're not entirely black and white - you also get 50 different shades of gray in between. Unless you're already a pro at handling a regular pair, the sheer size and weight of these triumphant bastards will wear you out a little quicker than usual. It's quite difficult to control them when stroking them around your palm and fingertips. The base keeps the balls tight to the cups, but for some reason I always get this reflex reaction when I turn my head and cough when I put them down.
