Anything it touches, it erases! If it only touches a pencil drawing. Pad is 2-1/2" x 2-1/2" x 1", filled with an erasing powder. Rub it over your drafting/pencil sketch/algebra exam and it'll erase for you. Also cleans grime off of your drawing surface before you begin. Superb for artists, draftsmen, and engineers.
