Tips

To replace a cartridge, simply unscrew the pen barrel, remove the empty cartridge, and insert a new one firmly until it pierces. Give the pen a gentle shake or wait a minute for ink to flow to the nib. Store unused cartridges in a cool, dry place away from direct sunlight to maintain ink quality.
