The qigong balls are said to have a great healing therapy on your nerves and are great for muscle tone in your hands wrists and forearms. As you rotate the balls in your hand, they chime and relax you. The balls are metal, hollow and have chiming sounding plates inside. Play them to relax and reduce stress. Beautiful silk covered box and instructions included.
When taking exercise, put the two qigong balls on your palm, and crook and stretch the five fingers in sequence to cause the balls to rotate and revolve, either clockwise or counter-clockwise.
