This is a large, high-quality sumi ink made from pine soot. It is considered a valuable ink because the production of high-quality pine soot ink has become difficult nowadays. It has a very aged flavor and is suitable for light ink works. The retail price is 15,000 yen. I am selling unused ink that I purchased in bulk previously, as I cannot use it all myself. *If you purchase this ink along with other inks, you can get a 300 yen discount. Please let me know before you buy.* Size: Length 137mm, Width 35mm, Height 14mm Weight: Approximately 92.7g (Approximate size and weight)
