This is a kneading bowl (konebachi) made from a ginkgo tree. It has been used about 10 times. I think it's still of a quality that can be used. It can also be used for interior decoration. The type of wood is unknown, but like a ginkgo cutting board, a wood "sap" has come out. There is no particular smell. Outer diameter: approximately 41cm Inner diameter: approximately 37cm Height: approximately 11cm Weight: approximately 2kg Soba noodles Buckwheat noodles
