Wristball is an artificial power device, which is purely mechanical, without batteries, any power supply and electromagnetic radiation. Wrist rotation drives the ball core to rotate at high speed, thus generating powerful force.

It is especially suitable for people who like sports and need the explosive force of wrist, such as basketball, tennis, badminton, table tennis, billiards, gateball and volleyball.

When there is 7~8 cm left in the rope, stop rotating the ball core, remove the thumb to hold the ball tightly, pull the rope outward quickly to make the ball core rotate quickly, then turn the wrist downward and gradually exert force until you can feel the speed of the ball core increase.
