DiamineFountain Pen Ink, Oxblood 30 ml

This works great in my Beiluner fountain pen. Smooth writing and very interesting color, like slightly dried blood, not bright red like fresh blood. Not as water resistant as I would like, but it didn't say in the description that it was waterproof, so I can't complain too much. over all I would recommend!

This is an excellent ink. Very unique and has a lot of personality. It has the intensity of red, but also a darkness to it that calms it down. Whether it's used in a finer nib or a larger nib, it stands out.The only downside is that it can take some time to dry.

My favorite color from the diamine company. Dark, rich deep red. I rebought many times. Love the ink, love the company.

Flows well and smoothly. The green color is very dark and saturated to the point of a slightly greenish black. It is only slightly noticeable as not-black under the brightest office lighting.

I recently learned that most fountain pen ink is acid and will melt the silicone ink sacs in vintage pens. Diamine ink, however, is NOT acid. I don’t know what the PH is, nor do I know who tested it, but the good people of r/fountainpens highly recommended it.I love it. It sucks right up into the pen. The bottleneck is big enough that I can just stick the whole pen in (with the converter attached) and suction the ink straight up. Then the pen is primed and ready to go.I haven’t experienced any bleeding, and (ironically) the only time it has smudged is when I was writing this review. The color is really nice; it’s not an obnoxious orange, but more of an autumn color.For the price, you get a lot of ink. As someone who changes colors often, I’m glad I can just buy a little bottle that won’t go to waste.

It is a nice light brown color. Works well in me Monteverde Monza pen

Love this ink. Writes really well. When it dries it looks like a faded brownish red, like a sun faded vintage store sign or something. Do be aware if you spill it and clean it up it looks like a murder scene lol

I have been looking for the 'perfect" green, something that resembles the fresh green of May leaves before they darken to withstand the sun's heat. I call that "May green". This ink is exactly that green. I am in absolute love with it and wish they would make a full size glass bottle of this wonderful ink. Needless to say, being a water based ink it is also water soluble as most inks are. Just thought I add that since I keep seeing this question coming up time and time again.
