Important Notes: 1. The wrist ball is a relatively delicate exercise equipment; when using it, be sure not to drop it. 2. Avoid foreign objects entering the ball during use. 3. When the wrist ball is rotating at high speed, do not touch the inner ball with your fingers to prevent finger injuries. 4. Do not throw high-speed balls towards the human body to prevent accidents.
