This ink is suitable for light ink washes and has a somewhat subdued bluish-gray color with reddish undertones. It is a pure plant-based pine soot ink. In terms of its physical properties, it disperses carbon particles well, harmonizing clarity and cloudiness within a soft feel. Furthermore, it facilitates the separation of the core and bleeding, creating a three-dimensional effect, and adds a touch of purity and white light, enhancing its quality and making it bright and beautiful. Although unused, it has been stored for a long time, so please understand this before purchasing. Manufacturing Year: 1975 Release Year: 1977 Number Manufactured: 1290
