Black Chalk by TOKYO POWDER is made from magnesium carbonates that is combined with a special moisture reducing and food safe additive.

Various studies with the Black Chalk formula have shown that this chalk keeps hands dry much longer than other chalks and offers excellent friction!

Due to its versatility, this all-round chalk is the first choice for many of TOKYO POWDER's athletes, as they are optimally equipped to meet the most diverse conditions on their climbing trips around the world.

The grain of the Black Chalk is quite fine, which makes it stick very well and quickly to the hands. So you can concentrate on doing your best instead of re-chalking.

Through their experiments, TOKYO POWDER have found out that chalk in general can age and wear off over time. For this reason the Big Pack (330 g) packages of TOKYO POWDER have a one-way valve. This allows the air to be forced out of the pack and the chalk stays fresh longer! In addition, the valve prevents the pack from bursting so easily.
