Udon and Soba Mixing Bowl / Sushi Oke (Sushi Tub) Diameter: Approximately 28cm Depth: Approximately 7cm - Color: Red and Black - Shape: Round Thank you for viewing. This is a mixing bowl that my parent used. I believe the material is plastic. It's not too big and doesn't take up much space. How about using it as a sushi oke for chirashi sushi? There is a feeling of use and minor scratches, so please refrain from purchasing if you are sensitive to these details. Please check the photos. Instant purchase is welcome. (^^)
