How to use
To replace a spent cartridge, open the pen according to the pen manufacturer’s instructions, remove the empty cartridge and insert a new Donau blue cartridge until it seats securely. Reassemble the pen and test on scrap paper to ensure ink flow. Store unused cartridges in a cool, dry place and avoid exposure to direct sunlight or extreme temperatures to preserve ink quality.
Usage recommendations
For best performance, use the cartridges with pens specified to accept short-format ink cartridges and allow a few seconds for fresh ink to start flowing after installation. If intermittent flow occurs after long storage, gently prime the tip on scrap paper.
