Chinese exquisite antique inkstone, a masterpiece for calligraphy and ink painting. It has a retro atmosphere. Comes with a high-quality wooden inkstone box. Perfect for calligraphy and ink painting. I am selling it because I am moving soon. I collected it as a hobby, and I believe it is unused, but there may be some age-related changes due to home storage. There are no major scratches that I can see. On the back of the wooden box, it says "[Made in China .56 40.000]". Is .56 a lot number? Is 40.000 the price? I think so. I am storing it at home, so I would appreciate it if someone who understands this would purchase it.
