The Sorinex Mighty Mitts Grip Chalk is the only American made chalk on the market. Our chalk is lab-grade magnesium carbonate, it is denser than most chalks meaning there is more usable chalk in each block and less brittle which means it won’t fall apart when stored and less is wasted in the air when broken apart.
