Aitoh Boku-Undo Sumi Inks

100 mL bottle of liquid sumi ink for brush painting and drawing.

Made of Sumi paste ink from pine soot and synthetic glue. It has a low level of salinity which is good for brush bristles.

This sumi is a very concentrated solution and not meant to be used straight from the bottle. It must be diluted with at least three parts water. This will give a range of transparent tones. Use water that is 68 degrees F/ 20 degrees C to make the best light tone of sumi color. Wait for a period of time after thinning for a more transparent tone.

This sumi cannot be mixed with stick ink.
