To use, insert a cartridge into the fountain pen by removing the pen cap and unscrewing the barrel. Push the cartridge firmly into the pen's ink reservoir until you feel it puncture. Screw the barrel back on, and allow a few moments for the ink to flow to the nib. Replace cartridges as needed to maintain smooth writing performance.

Store cartridges in a cool, dry place away from direct sunlight to prevent ink degradation. Avoid exposure to extreme temperatures which can affect ink quality. If not in use for extended periods, remove the cartridge from the pen to prevent clogging. Dispose of empty cartridges responsibly according to local recycling guidelines.
