Thirty-seven pieces covering five lead widths from 0.3 mm up to 2 mm, with a deep stock of refills. The 0.3 mm is the specialist here: it draws a truly fine line for technical and architectural work, and it breaks if you press the way you would with a 0.7 mm.

Care & Use
Keep each lead width in its own tube and label it — loose leads are indistinguishable by eye and a wrong-width lead will jam a barrel. Clear a jam with the cleaning pin in the eraser cap rather than forcing the clutch. Never dismantle the clutch mechanism.
