By taking the harmony of the clarity and muddiness of the ink stick, its clarity is the elegance and muddiness its thickness. We gave it three-dimensionality, and finished it as a calm color overall. For the light ink stick, there is no flashiness. However, there is warmth and clarity, and it is a beautiful refined blue with a shade of gray blue and a small amount of blue. For the thick ink stick, there is thickness without luster. It is a refined blue-type black with strong shade of blue. It can be used for hanging scrolls in kanji, small number of characters, and kana. Thick to extra light ink sticks can be used. As it gets older, we believe the ink stick calms in color, and its three-dimensionality, sharpness, personality, and features grow stronger. Manufactured in 1994
