Diameter: 34.5 cm Depth: 4 cm Rim thickness: Approximately 0.5 cm. This is an old item that has been stored for a long time without a box. I believe it is lacquered, but the material is unknown. I think it was used a few times during tea ceremonies. There are small scratches on the inside and outside surfaces. Regarding shipping, if I don't have a suitable cardboard box, I will use cushioning material and a thick paper bag. Please understand the above before purchasing.
