Their history is long, and there are various materials and shapes, but when rotated, they make a clear metallic sound. They also have value as beautiful crafts decorated with cloisonné. Health Balls have a long history as one of the three treasures of Baoding. They were first invented in the Ming Dynasty (1368-1644). They have been constantly improved by Chinese craftsmen over time. Initially, they were simple cylindrical lumps, but later craftsmen processed them into hollow balls. Thanks to this, they became easier to handle and could be used by people of all ages. In addition, by putting small pieces inside the hollow, they were improved to make various sounds during use, and the sound produced a relaxation effect, pushing the Health Balls further into sophisticated health tools. ⭐️ How to Roll Just place two balls in the palm of your hand and roll them around. Start by trying with one hand without overdoing it. When the balls hit each other, they make a pleasant sound, and if that becomes a constant loop, it becomes a pleasant rhythm. Don't just favor your dominant hand; be sure to roll them with the other hand as well. Also, don't forget to roll them clockwise and counterclockwise. It is very important to roll them in a balanced way with both hands, left and right. When the balls are rolling nicely, you will naturally find your posture straight. Once you get used to it, try rolling them with both hands at the same time. ⭐️ Diameter: Approximately 4.5cm
