Chinese Antiques [Old Shoushan Lotus Pond] Precious Seal Stone Rare, High-Grade Natural Seal Material with Natural Lotus Pond Stone Vein, 2-Piece Set Very rare. Purchased in 1987 at Liulichang, Beijing, famous for the Four Treasures of the Study. The number of seal stones has increased too much, and I can't use them all, so I'm offering them for sale in the hope that someone else will. Although it is new and unused, it has been stored at home for a long time, so I would appreciate it if you could understand this.
