Final price. Please refrain from price negotiations, except for a discount on shipping costs for bulk purchases. Size: Diameter 25.5cm, Height 4.6cm The design is so intricate it almost hurts the eyes. Insect-eaten patterns are applied to both the front and back. According to the young antique dealer who sold it to me, the insects really did eat it while it was stored in a warehouse... There is a mark on the center of the back, but I am uneducated and cannot read it. I cannot determine if this elaborate work is of Chinese or Japanese origin. There are no significant defects. Please purchase if you understand from the photos.
