Noodler's Air-Corps Blue Black
Pen: Lamy Safari EF
Paper: Rhodia Dotpad 80gsm
Noodler's Air-Corps Blue Black caught my eye very early on as a very interesting green/blue ink. I tend to avoid blue inks for whatever reason - I'm still not sure why - but I do love blue-black inks. Air-Corps Blue-Black is a bit closer to a green-black than a blue-black, but if you squint at it on paper, it'll kinda jumps back and forth between the two. That phenomenon is one reason that I really love this ink.
Being as dark as it is, ACBB has very little shading, though that doesn't take away from its character. It's a great ink for the professional environment; it's subdued, but different enough than your typical blues and blacks. It behaves well on my Rhodia pad, with no feathering, bleedthrough or ghosting. Cleaning from my Z24 converter was a breeze, though I will say I didn't have the ink in there for too long.
I highly recommend this ink, especially if you are like me and like inks that stray from the "norm." You can pick up a bottle from Goulet or a similar vendor for $12.50.
