Mirikeshi Variable-Width Eraser

Designed by 72-year old visual designer Yuji Baba, the Mirikeshi boasts 5 different edge widths - 6mm, 5mm, 4mm, 3mm and a point – to optimally erase from a variety of ruled notebooks. As an added bonus, as soon as the edges wear down a slice can be detached, revealing brand-new sharp edges.

A great tool that enables you to erase tiny strokes in your kanji without messing up the whole word.
