发明名称 Eraser holder
摘要 An improved eraser holder on a pencil includes an eraser support band which can be removed in incremental sections to provide access to additional portions of the eraser after the original exposed portion has been worn down. Fracture lines on the band facilitate incremental removal of the sections, and the fracture lines are axially misaligned to strengthen the holder.
