The OHTO Super Promecha mechanical pencil is a customizable drafting pencil that can retract the lead tip with a twist of its barrel. By turning the gears on the pencil, you can adjust the length of the lead sleeve (0-4mm) as well as the amount of lead that pushes out with every click (0.2-2mm). If you like, you can also detach the clip on the body of the pencil, and a lead grade indicator on the eraser cap functions as a reminder of what kind of lead you loaded in the pencil.
As a drafting pencil, the Super Promecha fixes the lead sleeve at the length you desire so that you can use a ruler, stencil, or other drafting tools to draw sharp, precise lines. The textured metal grip is slightly weighted so that the pencil maintains a nice balance as you use it. These thoughtful qualities make for a sleek and practical drafting tool that looks great and works even better.
