SumoGrip Premium Erasers work like ultra-fine sandpaper to get into the small grooves of paper and grab and trap erased graphite. Check out this video where artist Lemia Crescent uses the SumoGrip Premium Eraser to play with highlights, textures, gradation in tone, and to create contrast between light and shadow in her graphite illustrations. She also uses the Sakura Gelly Roll Pen in Classic White to create highlights and to make the drawing pop.
