Kokuyo 28-Corner/Kadokeshi Eraser
Kadokeshi is a Japanese combination of the words, corner (kado) and eraser (keshigomu). The 28 corners of this eraser ensure that there is always a sharp corner and straight edge for precise erasing. Designed by Hideo Kambara, the Kadokeshi eraser is both aesthetic and practical. This eraser was included in MoMA’s 2004 “Humble Masterpieces” exhibition and now exists as part of the Museum’s permanent collection.
