Using the Black Diamond Mondo Chalk Pot is easy. First, open the roll - top closure and put your chalk inside. You can place your climbing brushes in the brush pockets and keep your phone and keys in the zipped pocket. When you're on the move, simply close the roll - top to prevent chalk from spilling. As for maintenance, you can wipe the chalk pot with a dry cloth to keep it clean. If it gets really dirty, you can hand - wash it gently with mild soap and water. Just make sure to let it dry completely before using it again. Also, be careful not to drop the chalk pot too hard as it might damage the magnetic closure.
