Use the thumbs of both hands to press the inner ball and move the thumbs in the direction of the arrow to start the internal spring. The working principle is simple and environmentally friendly. By rotating the wrist, the ball core rotates at high speed, generating centrifugal force that makes the wrist feel a certain resistance.
