Ink eraser
(重定向自Ink Eradicator)
An ink eraser is an instrument used to remove ink from a writing surface, more difficult than removing pencil markings. Older types are a metal scraper, which literally scrapes the ink off the surface, and an eraser similar to a rubber pencil eraser, but with additional abrasives, such as sand, incorporated. Fibreglass erasers also work by abrasion. These erasers physically remove the ink from the paper. There is some unavoidable damage with most types of paper and ink, where the paper absorbs some ink.
