With no fillers, binders or drying agents, Spider Chalk’s American-made Mega Blocks are denser, cleaner and longer lasting than most standard import chalk blocks on the market. This formula includes only PURE laboratory-grade magnesium carbonate, which not only provides a dependable grip solution, but also stays dry even through high-intensity, sweat-heavy training.
Rogue offers Spider Chalk’s battle-tested Mega Blocks here in a set of 3 blocks, 5.5 ounces each, adding up to a little over 1LB of chalk per box..
