Tombow MONO Graph Mechanical Pencil

The MONO Graph Mechanical Pencil is Tombow’s #1 selling mechanical pencil. 

It features an innovative shake-mechanism that allows the user to extend the lead by simply shaking the pencil. The pencil’s clip is equipped with a shake lock that prevents accidental lead extension. 

Lightweight yet sturdy barrel with comfortable grip. A 4mm long fixed guide pipe prevents the lead from breaking and enables users to write firmly, stably, and comfortably. Features one of Japan’s most popular erasers, the MONO Eraser. 

Simply twist eraser to extend for use. Easy to refill both lead and eraser. Comes pre-loaded with 2 pieces of high-performance 0.5 mm HB lead.

The pen clip on the side functions as both a secondary lead advancement mechanism (pushed down) or a lead shake lock (pushed up).

Tombow's most popular MONO eraser is attached at the top of the pencil's twist-telescoping mechanism, providing greatly improved erasing performance. The eraser top also pops off for lead refilling.

Choose from Classic, Black, or Blue. Also available, the eraser refill 3 pack.

Add on the eraser refill pack and you'll be set for study. Takes any 0.5mm replacement lead of your choosing.
