S.T. Dupont Fountain Pen Piston Converter

The S.T. Dupont Piston Converter allows compatible S.T. Dupont fountain pens to be filled directly from a bottle of ink, providing a reusable alternative to disposable ink cartridges.

Its twist-operated piston mechanism draws ink smoothly into the transparent reservoir, making it easy to monitor the remaining ink level. The converter can be removed for cleaning or when switching between different ink colours.

To fill the pen, connect the converter securely, immerse the nib completely in the ink and turn the rear mechanism to draw ink into the reservoir.
