How to use: Simply open the drawstring of the chalk bag, dip your hands in the chalk to keep them dry and get a better grip while climbing. There's a brush holder on the side where you can place your climbing brush. To wear it, adjust the waistband to a comfortable tightness. Attention: Don't overfill the chalk bag as it may cause the chalk to spill out. When not in use, keep the drawstring tightly closed to prevent chalk from leaking. Maintenance: You can gently shake the chalk bag outside to remove excess chalk. If it gets dirty, follow the washing instructions on the label. Usually, a gentle hand - wash in cold water is enough, then let it air - dry.
