Professional Japanese black ink produced on the same high-quality components as traditional Sumi ink in bars, but in a more convenient, cleaner and more economical form. It does not smudge under the influence of alcohol markers, such as, for example, Promarker or Kurecolor Twin S. It dries slower than eg Black Ink 60, which allows you to work more freely. Can be used with both nibs and brushes. Capacity 60ml.
