3. More Chalk - Spider Chalk Mega Blocks are 220 grams per block, 3x the density of standard blocks.
4. Pure Chalk - Other blocks turn slimy when you sweat. We use only magnesium carbonate with enhanced drying ability even in sweaty environments.
5. Made in the USA - All conventional 2 oz blocks are made in the same factory and private labeled. We are the only chalk company that manufactures blocks in the USA, and we're proud to make Mega Blocks at our facility in Atlanta, GA.
