Setup, Compatibility & Care
Setup: To install a cartridge, unscrew the pen's grip section from the barrel. Remove any old cartridge or converter. Insert the new Diamine cartridge into the nipple, ensuring it is firmly seated. Some pens may require you to gently push the cartridge to pierce its seal. Reassemble the pen by screwing the grip section back onto the barrel. Allow a few minutes for the ink to flow down to the nib, or gently prime the feed by twisting the converter slightly (if applicable) or by touching the nib to a damp cloth.
Compatibility: These cartridges use the international standard short format. They are compatible with most fountain pens that accept this standard. They are NOT compatible with Parker, Cross, Sheaffer, or Lamy fountain pens, as these brands use proprietary cartridge systems. Always check your pen's specifications if unsure.
Care: When changing ink colors, it is recommended to flush the pen thoroughly with cool water to prevent ink mixing. Store unused cartridges in a cool, dry place away from direct sunlight. While Diamine ink is water-based, it's advisable to clean any dried ink from the nib and feed periodically to ensure optimal ink flow.
