The eraser that makes a case for making mistakes. Koh-i-Noor’s Hexagon Erasers bring the angular precision of the Czech stationer, founded in 1790, to a vibrant set of colors that looks as good on a desk as it performs on paper. The hexagonal form provides precise control for detailed work, in rich purples, warm reds, and crisp whites. Set of three, available in two colorways, made in Czech Republic.
