What is an art gum eraser?

An art gum eraser is a soft, pliable eraser commonly used by artists and students for removing pencil marks without damaging the paper. It is made from a rubber-like material that crumbles as it erases, effectively lifting graphite while leaving minimal residue. Art gum erasers are particularly effective for creating highlights or softening lines in pencil drawings. They are available in various shapes and sizes, catering to different artistic needs.
