Enameled metal exercise balls with a yin yang design, each is 1 1/2 inches in diameter. Rotate these balls in your hand for coordination and flexibility and also to hit the pressure points on your hand that correlate to your major organs in your body. The decorated metal balls are 1-3/4 inches in diameter and come boxed in a set of 2. These blue enamel balls have a black and white yin yang design around each ball. The metal balls make a slight jingle noise while you rotate them in your hands. Outer box colors may vary.
