6-Pack Fountain Pen Ink Cartridges

Designed to pair seamlessly with the Kolo Tino Fountain Pen or pens that take standard international short ink cartridges, like Kaweco's Sport Fountain Pen, this 6-pack of cartridges is filled with rich, water-based ink that flows with effortless consistency. Made in Austria and housed in sleek black cylinders, each cartridge is a precision-engineered refill that keeps pace with your thoughts. Whether you’re outlining your next idea or revisiting an old one, they make the act of refilling feel more like a reset. Keep them close — brilliance has a habit of striking more than once. Note: If exposed to freezing temperatures for a long time, the ink inside the cartridges may freeze and expand, bursting the cartridge.
