Kuretake Comic Black Ink 60 - 60 ml Bottle

Since no one else has written a review, I went ahead and bought this ink to try out.

Unfortunately, this ink is not that waterproof as it describes. With not too much effort it will lift off the paper and blend with water. It's also not as dark as Kuretake's other black ink (http://www.jetpens.com/Kuretake-Manga-Pen-Ink-60-ml-Bottle-Black/pd/4735).An d if this is like any other sumi ink as it is described, I wouldn't put it into a nib fountain pen.

Other than that, it's still a decent black ink. But, if you're looking for something more waterproof and darker (technically, really only if you're nit-picky as myself), then I would get Kuretake's other manga ink.
