Tombow - Eraser Pen - Mono Zero - Round - Silver
The silver Tombow Mono Zero is a high-precision eraser pen for pinpoint erasing. The ultrafine 2.3mm cylinder allows for correcting a single letter or detailed drawing, while the metal pipe prevents the sleeve from obstructing the view and allows visibility of the area to be erased.
The unique indirect chucking system extends the eraser by only 0.7 mm with each push. To refill the eraser, push and hold the knock button on the main body and insert the eraser with the plastic stick from the tip of the sleeve.
