Using the Mondito chalk bag is a breeze. First, open the roll - up top to access the chalk inside. You can place your hand in and coat it with chalk for a better grip during climbing. The brush holder is handy for keeping your climbing brush close at hand, so you can clean holds as you go. The pocket is great for stashing small items like keys or a snack. When it comes to maintenance, make sure to keep the bag dry. If it gets dirty, you can gently wipe it with a damp cloth. Don't overfill the bag with chalk to avoid spillage. And remember, always check the stitching and the integrity of the bag regularly to ensure it lasts a long time.
