Responsible and exclusive. We Care Chalk Bags are made from high-quality fabrics left over from the manufacture of other products. The chalk bag naturally offers the familiar proven Mammut quality. The shape-retaining opening allows easy access to the chalk, the drawstring closure provides reliable sealing and the lining reduces the formation of dust. An exclusive side effect of waste reduction: each chalk bag looks different and is a one-off! (Product color varies and may differ from the illustration.)
