发明名称 CHARACTER ERASER
摘要 PROBLEM TO BE SOLVED: To provide a convenient character eraser providing a light feeling of erasure without lowering character erasing properties. SOLUTION: The character eraser contains a polypropylene polymer polymerized by a metallocene catalyst. Since character erasing properties are not lowered and frictional resistance can be reduced between the sheet surface and the character eraser when a character is erased, light feeling of erasure is attained while enhancing convenience.
