Ever been frustrated at how wide the edge of your eraser is? Perhaps there isn't an edge wide enough? The Kokuyo Miri 5 could be the solution you've been waiting for. With 5 corners or edges, designed especially for erasing between the differing page rulings of Japanese ruled papers, the Miri 5 is a very versatile eraser. Once the corners of the Miri have been blunted the blunt section can be neatly sliced off with a sharp knife. The numbers denoting the edge widths run the length of the eraser, like a stick of Blackpool Rock. Eraser measures approx. 50mm long, 25mm wide.
