Pilot Fountain Pen Ink Cartridges feature a proprietary design that delivers precise ink flow through a 12-pack of either rich Black or Blue liquid ink.

These cartridges install in seconds with their tapered ends fitting perfectly into the grip section of Pilot fountain pens. When traveling or writing in the office, these sealed units eliminate the risk of ink spills that plague bottled ink users while maintaining the same writing quality. The cartridges' compact size allows carrying spares in a pen case, briefcase pocket, or desk drawer, ensuring your personalized fountain pen remains ready for use during extended writing sessions. Inside each package, you'll find 12 identical cartridges individually sealed in blister packs that preserve ink freshness for up to 36 mo
