Sumi ink is made from the same high quality materials as traditional sumi ink sticks. But comes in a more convenient, clean and economical form of a liquid. Think of the time and effort you will save when you don't have to grind your own ink! Sumi ink is made for brush calligraphy and paintings and is wonderfully dark and fluid. Great for sip pen calligraphy especially.
It's a very smooth flowing ink, smudge-proof with alcohol-based markers. Suitable for both professional artist and amateur hobbyists. This is a water-based Pigment ink.
