Kadokeshi eraser


Kokuyo's Kadokeshi eraser was a 2002 entry of the first ever Kokuyo Design Award. Its commercialization was realized one year later, and until this day it is a big hit. Featuring 28 corners there is always a fresh tip to erase with precision. As opposed to a traditional eraser with 8 corners that turns into a pebble-like shape over time. It refers to that moment when your eraser is still brand new, with its sharp corners that allow for precise erasing.

Kokuyo Design Awards: Making things from the perspective of the people who use them

"Kokuyo Design Award" started from 2002 and aims to make commercial products from the entries. From the award-winning artwork in the past, a total of 18 entries have gone from the contest to the market.

That feeling when you put pen to paper and let the ideas flow. Whether through stationery, furniture, or spatial design, Kokuyo strives to unleash people's inner creativity. Creation is an expression of uniqueness. Bringing out people’s individuality contributes towards a better future.
