Refill Ink Cartridges

Cartridge ink pen refills are user-friendly. The downside of fountain ink pens is that unlike cartridges, ink pots are not readily portable. Also, the liquid fountain pen inks tend to be messier than cartridges. You can buy refillable ink cartridges for use with India ink. Fountain pen inks in pots may be more charming, but for the pen enthusiast on the go, cartridge ink pen refills are the only option.
