Long Pimples
CK531A has inherited good characteristics of Chinese traditional long-pimple rubber since early 1960’s; however, it offers smaller and softer pimples with thinner sponge. Hence, it can create stronger reversed spins towards the opponents.

The pimples are a bit wider and longer than most long pimple rubbers and result in very troubling balls. The pimple surface is flat but not after-treated and therefore ITTF approved.
ITTF Approved.
Sponge Thickness: 0.6-0.8 mm
