Tombow MONO Graph Mechanical Shake Pencil (0.5mm)
The Tombow MONO Graph Mechanical Pencil uses 0.5mm lead from any brand. The shake mechanism allows you to pump lead out of the metal sleeve without have to click the eraser or clip. The lead can be pumped out in two different ways: shaking the pencil or clicking the clip. The pencil has a lead lock on the clip, so when you're storing the pencil lead does not pump out accidentally.
