Tombow Mono One Eraser

The Tombow Mono One is proof that even erasers can benefit from good manners and a slim profile. Shaped like a pen and perfectly balanced in the hand, it lets you erase with the sort of precision normally reserved for surgeons and crossword enthusiasts.

The fine tip deals calmly with single letters, stray digits and tiny pencil slips—never the surrounding work you meant to keep. A twist mechanism controls exactly how much eraser you reveal (no reckless overextension here), while the protective cap keeps everything neat between uses. Refillable and pleasingly compact, it’s a quietly brilliant addition to any pencil case, planner pouch or desk drawer.

Refills can be purchased here.

Precision in the Details

• Pen-Like Control: The slim, ergonomic shape always sits naturally in your hand, so you erase with accuracy, not guesswork.

• Pinpoint Erasing: The fine tip removes tiny marks cleanly—perfect for planners, notes, maths and detailed sketches.

• Made to Last: Refillable construction means you don’t replace the eraser, just the refill, which is both sensible and satisfying.
