About Pilot IC-50 Ink Cartridges

The Pilot IC-50 Ink Cartridge is the most convenient way to keep your Pilot fountain pen writing beautifully. Formulated in Pilot's Japanese laboratories, this ink is available in four essential colors: standard Black, traditional Blue, vibrant Red, and the fan-favorite Blue-Black—a deep midnight navy that offers the perfect balance of professional formality and unique character.

Packaged in a slim, travel-friendly box of six, these cartridges eliminate the need for glass bottles. When your pen runs dry, simply snap a fresh one into place. The ink flows instantly, delivering the smooth, uninterrupted lines that Pilot is famous for worldwide.

Most importantly, these proprietary cartridges are perfectly suitable for the Pilot Kakuno Fountain Pen. As the genuine refill designed specifically for Pilot's feed system, it ensures your pen performs at its peak without leaking or skipping.
