Thank you for viewing. This is calligraphy ink. It's Japanese ink. Unused. It's "Douchu Kappatsu" from Kyukyodo in Kyoto. It's quite old. It didn't have a box, so I put it in a new paulownia wood box. I think it's something that's difficult to obtain. Please check the size and weight in the photos. Please understand that it has been stored at a private residence. Would anyone who likes it be interested?
