Gum based erasers with added silica grit. These erasers gently abrade
themselves as you use them and work better than any other ink erasers
on the market. For best results use on better papers, such as that
used for resumes and books. Remove inscriptions and library markings
without making holes.
Also have been found to remove: crayon, dead bugs, stains, light
foxing, fingerprints and other such nonsense depending on the paper
surface.
