I own a rainbow of beautiful colors, mostly from Diamine, but what I really miss a a truly black ink for formal days. I have a big bottle of Parker Quink Black, but I almost never use it as it’s actually a middle-to-dark-gray ink even with my flowiest pens.
So what are your favorite, deeply saturated black inks?
Bonus points if it’s (very) affordable and easily available in Europe (so no noodlers).
How cheap is it in the EU though? Japanese pigment inks are very expensive to get for me (~25€ a bottle seems to be a good deal, not including shipping).
