This is a Seiboku (blue-black ink) "Seishishi" (3.5 chogata) from Kuretake Seishodo. It has been used only once, but I believe almost the entire amount remains. Length: 10.8cm × Width: 3.3cm × Thickness: 1cm Please allow for some size誤差. Price at purchase: 7,000 yen Current selling price: 11,000 yen <Quoted from the Kuretake website> Product features: A blue-black ink made by carefully selecting soot that has a bluish tint. A refreshing blue with a purplish tint. Suitable for kanji, kana, and ink painting. It is said that ink is better to use after it has been aged rather than immediately after purchase, as it will spread better and feel better when writing. This item has been carefully stored at home for over 15 years since its purchase. I'm not sure what kind of color will come out, but I hope you will enjoy using it. I am also listing Tenimuhou, Houn, Ganjun, and Kouun, so please take a look. #Spring7_sho #Spring7_all I am very sorry, but I would appreciate it if you would purchase it at this price.
