Fountain Pen Ink Cartridge - Blue/Black (6 per card)

Cartridges

Not much to say. Seems to flow well. Can’t wait to learn calligraphy and see how long the cartridge lasts! I’ll update later.

Interesting Color

I put these in when I ran out of the blue bottled ink. I didn't clean out the pen prior to switching and it's been interesting seeing the color change over time; it started out more blue and got darker over time. These are easy to swap out and just toss when done.

Beautiful ink color

I purchased ink from Amazon, and it did not work, so I contacted A.T. Cross, and purchased directly from them. They were a few dollars more, but guaranteed to repair my pen for free if the pen and ink didn't work perfectly. Of course, the ink was the answer! Works perfect, and I love using my fountain pen!
