OCEAN FILTERED GOODNESS

The Mg2+ chalk isn't just good for the planet—it's the perfect mix of chunky and fine textures.

It's like having the best of both worlds: the fine powder smooths out all those tiny skin ridges, while you still get that satisfying crunch from the chunks when you're battling the pump on your project.

Flash's Mg2+ process is pretty cool as well. They use ocean water pumped into baths, where magnesium slowly precipitates out over 20 days.

It's a slow and specialized process that only makes what's needed. The result? Top-quality chalk tested with XRD, giving max friction and minimal environmental footprint."
