Tokyo Powder Black Bouldering Chalk

This is the BLACK PACK from TOKYO POWDER INDUSTRIES.
This is chalk powder for bouldering and climbing.

BLACK is the signature chalk of Tokyo Powder, and it is their strongest all-rounder chalk, demonstrating high friction regardless of season or rock type.

It is said to provide satisfactory friction for both sweaty and dry hands in numerous situations.

I have been using the large pack, and there is about 170g remaining. This is more than the small size BLACKPACK, which is 135g.
The chalk is clean and free of moisture, so it can be used as usual.
