Nice black, doesn't feather on most papers
I got this as an alternative to Black Eel I been using for over a year. It provides a darker black especially in thinner/drier nibs. Doesn't provide quite as smooth the feel as black eel does, but it goes down black rather than a slight brown at the edge which black eel can sometimes do. On most normal papers it dries relatively quickly, on very smooth non-absorbent paper it can take longer than black eel.
