["Sakura sumogrip premium eraser Series features new microporous foam technology to remove graphite marks from paper surfaces for artists, students and architects. Sumogrip premium erasers are composed of microporous cells that constructed like a net that picks up graphite marks and erases better across the surface. Reticulated open-cell foam works like ultra-fine sandpaper to get into small grooves and pits of the paper surface. Combining our existing Sakura foam W eraser with a firmer hybrid-matrix formula, the sumogrip eraser requires minimum pressure to remove graphite lead. The sumogrip eraser vastly improves the pick-up of micro-graphite particles from paper substrates that white PVC erases leave behind.
