The Twin Hardball will allow you to improve your game by having much more sensations than with an ordinary ball.
This tool is not made to learn how to hit a billiard ball with strength.
This ball is heavier than an ordinary billiard ball (330g versus 250g) and allows you to learn how to give more spin and effect to your shots.
It will therefore be much easier for you to play with classic balls later on.
Ball diameter: 61.5mm
