The best ones are those from many years ago, a couple of which I still have,
designed to erase typewriter print when you screwed up. They are much more
coarse and abrasive than the little pink rubber things on the end of a lead
pencil. Of course, the best solution is some very fine-grit sandpaper -- one
ping only.
