Abstract: A holder for a pencil eraser with removable bands. As the eraser wears, connecting bands are removed, revealing more of the eraser. As the connecting bands are removed, they are replaced at the rear end so that the length of the eraser case remains the same. When the eraser is completely worn out, a new eraser is inserted in the eraser case.
