Electric Eraser & Refills: White Eraser Refills
This is one of the lightest, battery-operated, compact erasing machines on the market. Eraser and batteries weigh in at a mere 2.4 oz., and a surprisingly strong torque from the motor will satisfy most users. Its body design allows for easy control and handy storage. The basic kit includes the motorized unit, eraser chucks, two types of erasers and two AAA batteries. Packages of seventy eraser refills are available separately.
