How to use
Unscrew the barrel or remove the grip section according to the pen’s construction to access the cartridge or converter chamber. Insert a compatible standard ink cartridge firmly until it clicks or attach a converter and fill it with bottled blue ink, following the converter’s filling instructions. Reassemble the pen, allow a moment for ink to flow to the nib, then begin writing. Store the pen capped when not in use to prevent the nib from drying out.
Usage recommendations
For consistent performance, use compatible standard fountain pen cartridges or high-quality bottled inks when using a converter. Clean the feed and nib periodically with lukewarm water if ink color is changed or if ink flow becomes uneven. Keep the pen capped during breaks in use and store horizontally or nib-up to minimize leakage.
