Pen Converter St Dupont

A fountain pen refill that replaces your cartridge. You just need to fill the pen using an ink bottle, thanks to the piston system integrated into this fountain pen converter.

To replace the broken piston of your fountain pen or to have a spare.

• During the first use: using the black tip, turn counterclockwise to lower the piston.
• Dip the nib of your pen into the inkwell.
• Turn the black tip clockwise again to fill the cartridge.
