The Pilot Rotary Ink Converter (CON-40) is a practical and environmentally conscious accessory designed to expand the versatility of cartridge compatible fountain pens and allowing writers to enjoy the creative freedom of bottled ink with dependable everyday performance.
Engineered with a smooth twist-action piston mechanism, the converter draws ink directly into its reservoir with a simple rotation of the end knob. This intuitive 'rotary' filling system provides a clean and efficient refilling experience while allowing users to easily monitor ink levels through the transparent body. Internal agitator ball bearings help maintain consistent ink flow by reducing air bubbles and ensuring even ink distribution during writing.
With a compact design and reliable construction, the converter is compatible with many Pilot cartridge converter fountain pens, offering writers the flexibility to explore a wider range of bottled inks while reducing reliance on disposable cartridges.
