Pilot Parallel Pen Ink Cartridges, Mixable Color, Smudge Proof, Easily Refillable, Bold Color, Quick Dry, Ideal for Writing - Blue

The cartridges are engineered to fit Pilot Parallel Pen feeds. You replace the cartridge to switch colors, and the sealed design helps prevent leaks during use. They’re built to deliver reliable starts and consistent ink flow for parallel-pen lettering.
