Standard International Cartridge Diamine Rollerball Pen Refills in Blue
One thing to consider when selecting an ink cartridge is the length of the cartridge. Some standard international ink cartridges listed below, such as the Monteverde Magnum cartridge or the Pelikan Edelstein cartridge, will have the same size receptacle but the actual cartidge will be longer so they can hold more fountain pen ink. Not all fountain pens have enough room within the body of the pen to accept these longer ink cartridges.
