Round sushi oke made of natural wood, featuring a light color and Ichitoh-bori (single-knife carving). It doesn't leak water even when filled. I've only used it for chirashi sushi. I purchased it a long time ago at a local department store. Diameter: 36.5cm Inner diameter: 31.5cm Height: 10.5cm I remember it was expensive when I bought it. Thank you for looking.
