Benchmark® weight bags contain copper-coated lead shot sealed into polyethylene tubing which is then covered with an unbleached, unsized, soft cotton "sock". They are made in a flexible, loosely packed snake shape for many uses including book repair & flattening paper or textiles. Thin bags may also be placed inside fragile vessels to help stabilize them while on display.
