Wild Country Pure Chunky Chalk is 100% magnesium carbonate in a 1kg resealable bag, and nothing else. No drying agents, no fillers: just chalk formulated to coat evenly, stick longer and keep your hands properly dry between attempts.

It's as simple and effective as chalk gets. The chunky block format and resealable pack keep it fresh in your kit bag, and if you burn through chalk on long sessions or a drawn-out project, buying a kilo at a time is the fair-priced way to do it.
