Gyokuhin 3.0-chō (Boku-Undo)

The ink color is a slightly cloudy reddish-brownish black. When used thick, it becomes a powerful black with a reddish tinge.
This ink is suitable for kanji practice and final drafts on Hanshi or Gasenshi paper. It can be used in a range of thicknesses from normal to thick.
The older it gets, the thicker it can be used. It seems unsuitable for light ink.
