It seems this artist presented vases to the Imperial Family. It has been sleeping in a dark place for a long, long time. There are many of them being sold on Mercari (^◇^;) It has a moss green color like in images 1 and 2, with a matte surface and a calm color. Images 3, 4, and 5 are in sunlight. For those who like it. I will close the lid in the state shown in image 11, but it doesn't seem to close properly, so I will ship it with a secure packing seal.
