Thank you for your interest. Unused item from 1962. Made in Japan by Nihonboku, "Un'en Hido" (Cloud Smoke Flying). A certificate of authenticity is attached, stating it was made by Yozo Inokuchi, the first person in the ink-making profession to receive an Imperial award. Purple-black, ultra-fine particle manufacturing. Optimal for ink spreading. The current price is 27,500 yen, but considering the manufacturing year, it can be classified as old ink, and the manufacturer is also identified, so its value is considered high. - Manufacturing year: 1942 (Showa 17) - Material: Ebony - Accessories: Wooden box - Usage: Calligraphy tools - Character: Black wooden ink - Condition: Unused Thank you for viewing.
