  This is not just high-quality..., September 30, 2009
This is not just high-quality ink - it's an excellent dark black with great flow, that in my tests I find to be waterproof. Wow. A contender against Noodler's black... except with a smoother, juicier flow!

This ink is very interesting. It will make your pens write like a dream. It goes on nice and smooth, and doesn't feather, no matter how junky your paper is. It's light proof, as well as waterproof. If you want something to withstand anything you throw at it, this is the ink. It cleans off very easily with water, but does tend to leave a residue that can just be wiped off. It does have a unique smell, but if you've used any acrylic paints, it's 1/100 of that smell. It's pricey, but for those who demand it, there are no substitutes.
  I just received this..., May 10, 2014
By nan...
I just received this ink in a box of 12 cartridges. I was looking for a waterproof black ink to use in my Sailor calligraphy pens (used for sketching), and based on much research and reading many good reviews about this ink, as well as its successful use under watercolors, I decided to buy it.

I’ve tested it on the following papers: 1) Arches Watercolor (sheet), Natural White, 90lb, cold press; 2) Canson Montval Watercolor (pad), 140lb, cold press; 3) Strathmore 500 series Mixed Media (bound book), 90 lb, 4) Canson Art Book One Sketch paper, 67lb; 4) Bee Professional Series Pen Sketcher’s (pad), 70lb; and 5) Hewlett Packard Office Paper with ColorLok Technology (ream), 20lb.

On all of these papers, even with letting the Sailor Nano Ink Ultra Black dry for several minutes, I would definitely NOT plan to use it for line under watercolor. It leaves a grey wash on all the papers tested, some more than others. While it doesn’t run/beautifully wash like the ink that comes with the Sailor pens, it’s kind of the worst of both worlds.

It is also not as black as the ink that comes with the Sailor calligraphy pens (that’s a nice black!), and it’s a warmer color. In fact, in comparison with these pens/inks, I’d say this Nano ink lacks “character”, or “oomph”: Herbin Perle Noire (in a Rotring pen), Uni-ball Vision Fine (roller ball), Copic Multiliner 0.5, Platinum Carbon cartridge ink in a Platinum Carbon Desk Pen, Pentel Pocket Brush Pen, and the aforementioned Sailor ink that comes with the Sailor DE 40 degree Calligraphy Fountain Pen. (I don’t know what ink that is as it’s not specified anywhere).

So I am pretty disappointed. Since I’ve used one of the cartridges for testing, I can’t return this to Jet Pens. I am glad I did not purchase this ink in a bottle for $33! Anybody want 11 cartridges of this?

I love this ink. I use in in a Sailor Profit Calligraphy Pen. The pen with this ink is soooooo smooth, plus it is waterproof when I add watercolors. No feathering noted. Love it! I just wish it fit all of my fountain pens.

Top notch! Very dark black, good flow, water resistant, drys quickly on paper, won't clog your nib. Great stuff. You can get it in a bottle too.

  I don't really recommend..., March 4, 2012
I don't really recommend this ink.

This ink sometimes stays on your nib and does not go away,

so be careful if you are going to use it for an expensive fountain pen.

And the smell is too strong, it smells like some kind of dangerous chemical.
