GP 1945 Pen Addons — Refills, Stylus & Bit Driver

Upgrade and customize your GP 1945 Bolt-Action Pen with modular addons. Swap in a capacitive stylus tip for touchscreen use, add a hex bit driver for on-the-go tightening, or stock up on GP22/Lamy M22 refill cartridges so you never run dry.

All addons thread directly into the GP 1945 pen body — no adapters, no modifications. The modular design means your pen evolves with your needs: writer one day, field tool the next.
