Adjustable Bolt Action Pen

Modern Fuel machines these from a single block of solid metal — no plastic, no filler, no compromises. The bolt action mechanism has a click that turns into a small habit; the kind of thing you find yourself doing during meetings. Every cone and body are precision-mated at production, so the fit is specific to your pen. Ships ready to write.

• Each pen is uniquely fitted — yours and no one else’s
