Noodler's. Oh, Noodler's. Your cheapness depends on the stubbornness of one man. You haven't let me down yet. I mean, I've only tried two colors. But. Haven't let me down yet.
This ink is so well-behaved, it makes me wish any future children would be it. It has only feathered once in my entire time using it, and that was on some... stuff... that was either a tissue or toilet paper. During the second half of freshman year, this was all I used for pretty much everything.
It doesn't feather. It doesn't bleed. It's waterproof, bleachproof, shoot-it-into-space-proof. It takes a little bit to dry, which I think a lot of people have talked about before. I think it's because it turns concentrated as the liquid in the bottle evaporates. You could probably add some distilled water until it regains the consistency you like.
I love this ink, okay? It works perfectly all the time. I have never doubted the ink. Ever.
