Same 80/20 blend, but twice as much of it.
The details
Stash keeps you going for weeks to come so you can avoid trips to the store or be worry-free for those outdoor rock trips where running out of chalk is a bad thing to discover at the base of a boulder.
The blend works the same way. Fine chalk coats on the first dip. Chunky pieces keep breaking down as you go, so one chalk-up lasts deeper into the burn.
Crush it finer when your hands run moist. Leave it coarse when you want bite, or a piece big enough to tick a hold.
Nothing but magnesium carbonate. No drying agents, no fillers. The screw-top seals between sessions, which matters more on a jar this size, since it will be open and shut a lot more times before it is empty.
Packed in Vancouver, tested on Squamish granite.
