Pilot Fountain Pen Ink Cartridge

Pilot Fountain Pen Ink Cartridges are the low-effort way to keep your pen going without cracking open a bottle. Pop out the empty, click in a fresh one, and you’re back to writing in about three seconds, no paper towels or inky fingers required.

These are Pilot’s proprietary cartridges, made to fit pens like the Kakuno, Metropolitan, and Prera, with smooth, reliable ink that behaves nicely on most planner and journal paper. They’re perfect if you’re just getting started with fountain pens or want a grab-and-go backup for travel and pen cases.

At Papertail Fox, we love them as a “keep it simple” option: bottled ink for the desk, cartridges for when life (or your to-do list) is already chaotic enough.
