Diamine Oxblood is one of the company’s best selling inks in the world to the point where it can be downright difficult to get your hands on. The color is a dense red that is reminiscent of its namesake. Since the ink is so saturated, it bleeds like crazy on cheap paper, but there is almost no bleeding on Rhodia unless you are really trying to get it to bleed. The ink exhibits some lovely shading in broader nibs and is a very matte tone. I have noticed that even when dry, patches where a lot of ink has been deposited can still smear. The ink is not waterproof and is barely legible when exposed to water. It is a very wet ink, so dry times are quite long, even with fine nibs, and it looks much darker on more absorbent paper. But if you’re looking for a deep, blood red, then look no further. This ink met my expectations and more. One of the most often recommended dark red inks, Oxblood is a happy addition to any ink arsenal!Like what you see? Subscribe to our newsletter!
