Sumo-Grip Retractable Eraser Refills
The SumoGrip Retractable Eraser features microporous foam technology to remove graphite marks from paper surfaces for artists, students and architects. Reticulated open-cell foam works like ultra-fine sandpaper to get into the small grooves and pits of the paper surface. The SumoGrip Eraser requires minimal pressure to remove graphite lead from B to 2H degrees.
