I am looking for an eraser that is in the form of a pencil. Does anyone remember seeing something like it? It's for erasing really fine detail like when you are drawing or doing stencils etc. The eraser is like a pencil and really really thin, if the eraser is "dull" you can peel part of the pencil skin off and the eraser is sharper.

It is not one of these
