By giving it a slight muddiness with a beautiful color as our goal, we suppressed the darkness that the muddiness has, and created a refined color that is bright overall. For the light ink stick, it is an elegant and bright blue with a strong shade of blue. For the thick ink stick, 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, kana, and ink stick paintings. 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 year: 1993
