Pair of 45mm plain silver chromium-plated chiming balls in a presentation gift box. The box colour varies, and includes instruction leaflet.

Iron Health Balls have been used for hundreds of years in China, both by emperors and ordinary people. Regular use is reputed to calm the mind and body, and to prevent, alleviate and even cure some ailments. Originally the balls were solid, but then they were made hollow, each containing a chiming mechanism: one chimes a high note representing the 'yin' (the female, moon, the phoenix), the other a low note, the 'yang' (the male, the sun, the dragon).

Chinese medical theory claims that our fingers are connected with our heart and all the other main organs and that, by using the iron balls, acupuncture points on the hand can be stimulated, which in turn improves blood circulation and relaxes muscles and joints.
