This is a souvenir I received from China. In China, they are called "fitness balls" and are used in a health practice where you rotate two balls in the palm of your hand. There are two bells inside the box, and they make a beautiful sound when shaken, which is very soothing. I have kept them carefully stored in the box, so there are no noticeable scratches or damage to the balls themselves. However, the outer box has some wear and tear from age, with threads coming loose in places and the clasp being rusty. ● How to use: Place the two balls in the palm of one hand and rotate them up, down, left, and right with your five fingers. It is said to improve blood flow and have various effects, such as relaxing the hands. ● Prevention of hand and finger injuries, strengthening grip strength ● Rehabilitation, recovery of muscle strength and motor skills after surgery It is said to be used for things like these. ○ For those who understand that this is a used item, we look forward to your purchase. ○ Please feel free to ask if you have any questions. ○ Immediate purchase is OK. ※ Please read the profile before purchasing ※ #HealthBalls #KenShinBalls #FitnessBalls #ChineseSouvenir Thank you for viewing.
