Fully-Machined, Polished Brass

The most recent version of the Brass Bolt maintains the original external geometry of the pen, while making small engineering adjustments to improve function. The internal o-ring on the lower body keeps the pen from unscrewing while being carried in a pocket. Changes to the J-slot include moving it upwards as far as it can go to keep the pen under 5.5 inches in length; and the J-slot itself has been rounded more dramatically to draw the bolt into place when actuating the refill. Machined from solid C360 free-machining brass that is then hand sanded and polished, after which a liquid oxidation agent is applied that temporarily protects against patination. Ships in our recyclable packaging with a custom vinyl sticker.

Comes pre-configured with a black 0.5mm Pilot G2 refill.
