Noodler’s Apache Sunset became one of my favorite inks the first time I used it. Even though I tend to use thin nibs the shading abilities of this ink do show through. I haven’t experienced any feathering in my use.
This ink was made for my Gate City New Dunn pen, “Tattler” edition with a medium nib. I love the way the ink appears in the barrel. Because the pen comes apart so easily cleanup is a breeze, just remove both ends and flush water through. The ink also easily flushed out of the feed with just a couple flushes. The ink doesn’t appear as red on the paper as it does in the pen, where it almost looks to be a blood red.
So far the New Dunn pen is the only pen I’ve put this ink in.
