Tombow Mono Zero Eraser Round 2.3mm

The Tombow Mono Zero is a precision eraser built like a pen — designed for detail work where a standard block eraser is simply too big. The round 2.3 mm tip lets you erase individual letters, fix fine pencil lines, and work around intricate drawings without disturbing the surrounding area.

The slim body features a long metal chamber that keeps it stable under pressure while maintaining a clear sightline to the paper. Advance the eraser with a click at the top, and the trigger mechanism releases it in short increments so you stay in control. The body includes a clip for attaching to a notebook or pencil case.

Winner of both the Red Dot Design Award and the iF Design Award. Refillable with Tombow ER-KUR round refills (sold separately).
