This is a suzuri (inkstone). It appears to be of Chinese artistic origin, but its specifics are unknown. I purchased it online, but I haven't used it, so I'm listing it to declutter. I think it's cool not only for calligraphy but also as a work of art. It seems to have been used before purchase, so please understand that it is a used item before purchasing. Please refrain from purchasing if you are sensitive to the condition, as it has been stored by a private individual. Measurements (approximate maximum values): Length: 21.5cm Width: 14.3cm Thickness: 3.2cm, about 5.5cm including the lid Weight: Approximately 3kg Feel free to comment.
