This invention concept pertains to an eraser that would fit on top of a pencil, which started with a #2 pencil. The pencil eraser should be made with “a different type of rubber”. It was also used with other types of erasers, as well.
Later on, there was the "detachable pencil eraser", as well, which was an eraser that fit on top of a pencil, that could be removed, such as with a mechanical pencil, something that was also commented on, which could be removed to add lead to the pencil.
