[Size] Diameter: Approximately 10.5cm Height: Approximately 2.5cm *With the lid on. This was purchased in China over 30 years ago by my father, who practiced calligraphy. The material of the inkstone is believed to be Duan inkstone, but it is uncertain. It doesn't seem to have been used much, but there were traces of ink, so it has been cleaned. I think there is some slight wear and tear, but there are no noticeable scratches or stains. The box is deteriorated. Please check the images carefully and understand that this is a used item that has been stored for a long time before purchasing.
