Keep Eraser 1 Case 20 pieces per case Brand new, unused Price is not negotiable. Keep erasers have a moderate hardness, allowing for precise corrections and clean erasing without leaving eraser residue, making them suitable for high-precision work. They also have an easy-to-hold shape and minimal colored parts, so they won't distract you while working. However, Keep erasers are discontinued, and the quantity available in the market is limited. Therefore, it may be difficult to get a Keep eraser now, but once you try it, you may not be able to go back to other erasers! #Tokuchan'sRoom
