KAMUICHALK 0.98Kamui .98b “Beta” Chalk is back by popular demand. The original formula direct from Kamui. This chalk is constructed with finer particles than your standard chalks. They are designed to maximize friction and offer a larger “sweet spot,” which generates more spin to the cue ball. The added friction reduces slipping, miscues, and deflection. The end result: Your English Game Will Be Better Than Ever.
