Tombow Mono Zero Eraser Pen Refills fit perfectly into our Tombow Mono Zero Eraser Pen – Round Barrel 2.3mm. This refill pack contains two erasers.

The Tombow Mono Zero Eraser Pen is not your average eraser. The creators at Tombow very cleverly identified that when erasing such fine pencils lines your erasing tool should be equally as fine as not to ruin or accidentally rub out your hard work.

This round pen barrel is fitted with a 2.3mm perfectly round eraser that can be advanced forward with a simple click of the top. The eraser is incased in a protective metal shield at the base of the pen to ensure it does not break even when firm pressure is applied.

The Eraser Pen and Eraser Refills are also available in a rectangular shape.
