Sumi no Sei Jōfuku No.9 Purple 100g (Boku-Undo)

This ink expresses beautiful three-dimensionality (harmony between strokes and bleed) and transparency in light ink.
It is formulated to suit raw paper and processed paper for practicing and creating light ink kanji, harmonious writing, small character counts, and kana calligraphy.
It does not gel at low temperatures. To create beautiful light ink, dilute with water at around 20°C.
Although it is designed for light ink, it is designed to maintain a deep black color, so it can also be used at standard concentration.
It also works well in mounting.


When diluted 2-3 times, it is the opposite of azure-purple black. When diluted 20 times or more, it becomes a zure-purple ink with a well-balanced core and bleed, creating a three-dimensional effect.
Please dilute the product at a concentration of approximately 2 to 60 times.
