Sumi ink is one of the most favorite black inks suitable for calligraphy. It is a pitch-black ink with a nice substance for writing. This Sumi ink is very suitable for beginners. Sumi ink is known to thicken the ink over time. Has your ink gotten thicker? Then you can simply dilute it with a little water. If you want the ink to have a long shelf life, use mineral water when diluting the ink.
The Sumi ink comes in a nice jar with a wide opening and contains 45ml. Ideal because you can so easily dip your pen in the ink. Even when you have an Oblique holder, it fits well because of the wide opening.
