There's a reason serious drafters and illustrators keep coming back to the OHTO MS01. Machined from solid metal and engineered for precision, this is not your average mechanical pencil. The all-metal construction delivers a satisfying heft and balance that plastic-bodied pencils simply can't match — giving you the confidence to draw finer lines, hold tighter tolerances, and work longer without fatigue.

Frequently Asked Questions
