Part of the legendary Promecha family, the MS01 boasts all-metal construction - an aluminium barrel with chromed brass and steel components, with the only plastic being the inner lead holder. The weighty grip is knurled aluminium, approx 10mm diameter, and provides a firm grip without being rough. The cylindrical barrel is tough and durable and the MS01 is substantially weightier than its predecessor, weighing in at 27g. The strong steel pocket clip is removable. The metal push-button shows the lead size on the end and removes to reveal a replaceable eraser with clearing pin.

You can adjust the length of the lead pipe, and how much lead each click pushes out.

Approx dimensions: 151 x 10 mm

Refill with 0.5mm leads.
