By taking the harmony of the clarity and muddiness, we gave it a soft feeling overall. We also gave it three-dimensionality and warmth, and it is a refined color that is calm. For the light ink stick, a heartwarming warmth and a softness can be felt. It is a black with a shade of elegant red purple-type blue. For the thick ink stick, the muddiness becomes the thickness, and it is a refined black where a shade of blue can be felt. It has no luster. 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
