The Tombow Mono eraser comes with two options: full sand, or a combination of half sand half rubber.
The sand side of the eraser can be used to erase ink markings, including ballpoint and gel pen, fountain pen, marker, and printer ink. The rubber side can erase graphite from pencils.
This high-quality eraser is non-PVC and phthalate-free.
Note: As this eraser removes ink by sanding the top layer of the paper, we recommend using it with thicker paper.
