By slightly putting the weight on the muddiness with regard to the harmony of clarity and muddiness, its color is the thickness. By adding three-dimensionality and warmth, we finished it as a refined color with a calmness overall. For the light stick ink, it is slightly opaque. It is a calm blue with a shade of gray blue where a darkness can be felt within the brightness. For the thick ink stick, it is a refined blue-type ink stick with a thickness, 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.
