This set of fintage Chinese health balls are by historic Dacige brand and feature a classic orange enamel finish with black and white Yin-Yang symbols. Used traditionally for hand exercises and stress relief, both balls have a built in chime mechanism that makes a soothing sound when rotated in your hand. They come with their original fabric covered silk lined storage box, with a functioning clasp. Overall in good vintage condition, with minor discolouration / spotting on one of the balls. Both chimes work well.
