Chinese Inkstone, Tang Inkstone, Registered, Duanxi, Trademark, Plum Carving, Suzuri, Writing Utensil, Valuable Item This item is from the estate of my grandfather. There is some dirt on the exterior. I have no knowledge of inkstones, so I can't say much about the condition, but there doesn't appear to be any damage. My grandfather said it was a valuable item, and he rarely used it because he treasured it. The wooden box has a sticker that says "Registered, Duanxi, Trademark."
