Material: Bloodstone Category: beads / ball Shape: Round Hanging form: ornaments How to use: During exercise, hold the two balls in the palm and use the five fingers to make the two balls hover each other. The direction of rotation is smooth and reverse, so that all the joints of the hand are in motion. With the flexion and spread of the fingers, the forearm muscles can contract and relax rhythmically. Small models can be selected at the beginning of training, and after getting cooked, gradually purchase larger models. The two hands can alternately exercise, or three or four balls can be rotated at the same time to play several patterns. Size: Beads 50mm
