In an overall clear and bright feeling, we added three-dimensionality (separation of the core and bleeding), warmth (redness), brightness, and elegance. For the light ink stick, it is an elegant red brown purple-type color with clarity and warmth. For the thick ink stick, it has a sharp strength and depth, and it is a refined black with a strong shade of black. It can be used for kanji and kana in thick, medium, or light ink sticks. As it gets older, we believe the ink stick calms in color, and its three-dimensionality, sharpness, personality, and features grow stronger. Manufactured in 1991
