Tombow Mono Zero Eraser Square

The Tombow Mono Zero Square is the flat-edge counterpart to the round version — designed specifically for tasks that require a straight line of erasure. The 2.5 mm × 5 mm rectangular tip lets you erase along ruled lines, clean up edges, and make precise corrections that a round tip can't quite achieve.

Same award-winning pen-style body as the round version: a long metal chamber for stability and a clear view of the paper, click-advance mechanism with short increments, and a clip for easy carrying. Refillable with Tombow ER-KUS square refills (sold separately).

Note: the round and square refills are not interchangeable — make sure to pair with the correct ER-KUS refill.
