uni is the stationery line from Mitsubishi Pencil, a company that's been making pencils in Tokyo since 1887. The uni name has covered their pencils, pens, and erasers since 1958, all built for precise, repeated use.

This plastic eraser is designed so crumbs clump together as you erase instead of scattering across your desk, keeping cleanup quick. It measures 45 x 25 x 14 mm and comes wrapped in a paper sleeve, made from a synthetic eraser compound. Made in Japan.
