Kutsuwa Zikeshi Magnetic Eraser Refill. Pack 2 Units

Magnetic Eraser Refill 

The black eraser contains ferrite (iron powder). When erasing, the powder adheres to the neodymium magnet inside the pen (not included) and collects the eraser fragments.

Its 5 mm diameter makes it ideal for erasing small areas, even the finest details.

Made in Japan.
