Kamui has answered the feedback from many players that have been using the 0.98. The 1.21 still has the grab but is a harder compound. It also allows the player with a pre-shot routine to chalk more often. Less residue left on the cue ball as well. • Not abrasive to your tip • Coats evenly • Decreases miscuing • Stays on your tip longer • Increases friction on the cue ball KAMUI Chalk consists of much finer particles than standard chalk designed to maximize friction and offer a larger sweet spot to generate more spin to the cue ball. Reducing slippage decreases deflection, giving the player a more accurate aim when English is applied.
