J. Herbin Ink Cartridges Bleu Nuit

Love the blue/charcoal color. Beautiful to write with, but professional anywhere you can use blue ink. I love using it in my Kaweco Brass Sport.

I ordered and paid for a canister of six cartridges and only got five. Not cool.

Fantastic color, it's an amazing blue-gray tone that I've honestly never seen before. It's also not "flashy" blue, just a very distinctive blue that looks very mature.

Bought these because someone in another review said they fit the JinHao pens I bought from China. They don't! From now on I'm sticking to Waterman pens and inks.
