Sakura‚Äôs SumoGrip¬Æ Eraser series features microporous foam technology to remove graphite marks from paper surfaces for artists, students and architects. SumoGrip Erasers are composed of net-like cells that pick up graphite marks and erases better across the surface. Reticulated open-cell foam works like ultra-¬¨fine sandpaper to get into the small grooves and pits of the paper surface.¬†
Combining our existing Sakura Foam W‚Ñ¢ Eraser with a ¬¨former hybrid-matrix formula, the SumoGrip Eraser requires minimal pressure to remove graphite lead from B to 2H degrees. The new foam technology of SumoGrip erasers vastly improves the pick-up of micro-graphite particles from paper substrates that white PVC erasers leave behind.
