In an overall plain feeling, there is a harmony of warmth and brightness. We added three-dimensionality (separation of the core and bleeding) and thickness in color. For the light ink stick, we added brightness to what seems plain at first glance, and it is a complex and refined blue with a shade of faint red. For the thick ink stick, it is a refined blue-type black with thickness and absorbability. It can be used for kanji and kana in thick, light, or extra 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
