I was excited when Diamine announced their 150th Anniversary inks, especially because I would be able to add a new blue black ink to my ever growing ink inventory. Blue black inks are my favorite of course, and I couldn't wait to see how it stacks up with the rest of my stash.
Diamine inks are some of the most user friendly inks on the market. They flow well in a wide range of nibs and maintenance is a breeze. They offer up a massive range of colors, and are very well respected in a sometimes crowded market. The 150th Anniversary lineup fits in well with their other offerings, albeit a touch more expensive due to the "Limited" tag.
When I first inked it up I was concerned with how dark the ink was, and that feeling did not pass the more I used it. It is very pretty, but very dark with minimal shading. I prefer lighter, or at least more shaded blue blacks. If you like darker blue black you should give this a shot because, as expected, it performs wonderfully.
