Staedtler Mars Plastic Combi Eraser

The blue half is basically useless. Erases nothing- not ink, not pencil, not toner. And it's mostly blue so you're better off just getting a straight up mars plastic. At least it will be 100% useful. Oh we'll, I have a small eraser with a blue rubber handle now... :)

2/3 blue eraser that doesn't erase ink but is ok at pencil
not recommended

DO NOT BUY THIS!!! It DOES NOT erase ink, and if you do buy it and you say "oh I'll just use it as a regular eraser" you can't. If you take off the dark blue cover, it is 1/3 plastic eraser and 2/3 blue rubber.
