Stored items from my parents' home. The wood type is unknown, but the hoops appear to be made of copper. I usually used a larger size sushi rice tub, so I think the condition is good, but there are water droplet marks on the hoops. The color doesn't seem to be dull. Outer diameter: 34cm Inner diameter: 31.5cm Height: Approximately 9cm Please take a look at the images and consider purchasing.
