The Sang Lee chalk is a very high quality billiard chalk. It is used and endorsed by Torbjörn Blomdahl.
Anecdote: Cue tip chalk was invented in its modern form by the billiard pro player William A. Spinks and the chemist William Hoskins in 1897. It is made by crushing silica and the abrasive substance corundum or aloxite (aluminum oxide).

• A chalk too smooth is not synonymous with high-quality
