Gum erasers manufactured from a synthetic rubber that has a high capacity for the absorption of charcoal and graphite and any dry media. They erases easily without exerting pressure on the surface of the paper, forming soft crumbs. As it crumbles it creates a fine dry powder which cleans the surface by absorbing dry media and dirt. It can also be used to erase or blur strokes of charcoal drawings. It keeps the paper surface unscarred.
