- The product includes: JIN BD wrist ball Blue LED light model, brand card, ball bag, safety rope, instruction manual, gift box
- Automatic Start:This upgraded version features a built-in pre-tensioner for activation—no starter string required. Simply press the inner ball with your thumb and move it in the direction of the arrow to engage the internal spring. The mechanism is simple and eco-friendly. As the wrist rotates, the core spins at high speed, generating centrifugal force. The faster the spin, the greater the resistance, allowing the wrist to experience an effective workout.

By continuously and indirectly strengthening the muscles and flexibility of the forearm and wrist joints, it can significantly improve muscle strength, flexibility, and promote blood circulation.

- Quality Assurance: JIN BD Torsion Ball is rigorously tested by factory machines, warehouse inspections, and manual re-inspections. This product does not require battery power. Wrist rotation interacts with the internal ball core to generate centrifugal force to maintain efficient rotation. The faster the rotation speed, the greater the force generated.
