The MOO Eraser is great for erasing pencil, graphite, charcoal and other media without damaging paper. It's a soft yet dense eraser and rather than creating eraser dust, it produces a long roll of erased material that is easy to remove and clean up. Can be used like kneed-rubber for stamping/touch up sketching.
