Wild Country Pure Chalk Block is a 58 gram block of pure magnesium carbonate, crumbled by hand into a chalk bag. Wild Country make a point of what is not in it: no drying agents and no additives, just the carbonate itself.

• 100 percent magnesium carbonate: no drying agents, no fillers, no additives of any kind.
• 58 g block: broken up by hand, so you control how fine the chalk ends up.
• Less dust than loose chalk: a block travels and stores without the cloud that a bag of powder produces.
• Even coating: the reformulated block is made to crumble cleanly rather than into hard lumps.
