By slightly putting the weight on the muddiness with regard to the harmony of clarity and muddiness, the clarity is its elegance. By giving it three-dimensionality using muddiness as its thickness, we finished it as a refined color with a strong shade of blue overall. For the light ink stick, it has a strong three-dimensionality and thickness. It contains a bright blue within a darkness, and it is a heavy blue where its weight can be felt. For the thick ink stick, it has thickness and strength in the color, and it is a blue-type black with a strong shade of blue and absorbability. 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 1995
