Well, I feel a little bad about posting a review of an ink that is most likely unobtanium. A sample was sent to me early last year, and I've only now gotten to actually trying the ink. It was apparently a Noodler's custom ink for perhaps a Swedish Pen Club. I don't remember the exact circumstances surrounding this ink. I don't know if it was a one-off, or something that is restocked. Perhaps there is someone in Sweden or Stockholm who could clarify matters.
A vintage style blue kind of like a royal blue. This ink for some reason seemed dry to me, which usually isn't the case with Noodler's. The ink dries almost instantly, and is totally waterproof. I forgot to do a chromatography before I emptied the pen.
The pic for the Mohawk via Linen is very accurate to my eyes comparing on screen and on paper.
Here the ink looks brighter and darker, almost like PPS, which this ink definitely is not.
