When purchased, this carving was reportedly hidden by ink and couldn't be seen. The buyer, confident it was "Old Duan Inkstone" due to its soft texture, decided to buy it. After taking the time to remove the ink, "this unknown creature?" appeared. It feels smooth and soft to the touch. This item belonged to my older brother, who has practiced calligraphy for over fifty years. Most of the items were purchased and stored decades ago. It's said that ink, paper, and inkstones develop a good texture with age. I don't understand any of it! There are too many items, and it takes time to research them. I was asked to list them gradually. I'm also listing inkstones, old ink, seal stones, etc.! I would be happy if you could take a look when you have some free time. Thank you for viewing.
