Like other Power Balls, this |
Power Ball also provides a delightful, relaxing and extremely effective way to improve your grip, strengthen your wrists and arms and improve your coordination without strenuous exercise.
In addition, this Power Ball has a generator inside and will glitter as long as it spins. It uses no batteries, no electricity and no chemical matters. The ball glitters by the dynamism the user's hand makes. It's the magic physical phenomenon to make the ball glitter. The light even makes the whole palm become red, becoming very shiny at night.
Since there are no batteries, it will always glitter as long as no damages are caused to the ball.
