This ink is exactly what I wanted it to be. It is currently my favorite, and even though I have plenty of new offerings waiting in the wings, I've inked up with Oxblood twice in a row. I was lucky enough to have a friend send me a written sample of this ink before purchasing it, so that I could see it in person. I am so in love with the color, it looks just like fresh, oxygenated blood. It is an absolutely gorgeous dark red, great for Fall and the Holiday Season. There is enough "blue" to this to make it a brilliant, true red, and keep it from leaning towards brown. There's also not so much blue that this leans toward burgundy or purple.
Flow is very good with this ink, especially in the Sheaffer Imperial I put it in today. There is no feathering or bleed-through in a Lamy Safari 1.1 italic nib, but my medium Sheaffer nib is so wet that it does feather very slightly on Rhodia. Dry time is not great, but not really much worse than any other ink I've used. Waterproof-ness is on par for a non-waterproof ink. This is a super saturated, dark ink, so shading isn't very apparent.
I can't say enough good things about this ink, it matches my new pen wonderfully, and the two together put me on cloud nine.
I will most certainly be using this ink for Christmas cards, and lots of personal correspondence and journal entries. I wouldn't really deem it appropriate for business use, but if you use red ink to edit or annotate, this would be an excellent option for something just a bit off the beaten path. If you're a pen-pal of mine, you may have already seen this ink. If not, expect to! =)
This ink came from the lovely Goulet Pen Company (who, though not affiliated, I also cannot say enough good things about).
