Mondo Chalk Pot from Black Diamond is a chalk bag for boulderers.

The chalk bag has a very stable design and magnetic closure to minimize the risk of chalk spilling out. The bag features brush holders for various types of brushes. There is also a zippered pocket where you can store your mobile phone or other important small items you bring with you to the blocks. The roll-top closure keeps chalk inside the bag when packed, so you avoid chalk on all your gear in the bag. 

The REPO fabrics are made from leftover material so each bag is unique.
