Kuro Sumi — meaning "black ink" in Japanese — has been the gold standard for black and grey tattooing for decades, and remains the first choice for artists working in Japanese traditional, black and grey realism, and dotwork styles. The ink is carbon-based, drawing on traditional Japanese sumi ink-making techniques, which produces a depth and richness that synthetic blacks rarely replicate.
The grey wash series is particularly respected. Pre-diluted in five consistent values, it allows smooth, predictable gradient work without the inconsistency that comes from manually watering down black ink. For portrait artists and black and grey specialists, having reliable, repeatable grey values ready to go significantly speeds up complex work.
Kuro Sumi's colour range, while not as extensive as some brands, delivers the same boldness and longevity as their blacks — popular for bold Japanese colour work and traditional American pieces. Shop individual bottles and sets below.
