Sakura’s SumoGrip Eraser series features new patented foam eraser technology so that minimal pressure is required to remove graphite marks from paper surfaces. The erasers are composed of micro porous cells that are constructed like a net that picks up graphite. The reticulated open-cell foam works like ultra-fine sandpaper to get into the small grooves and pits of the paper surface without harming it.
