Sushi oke (sushi tub) - Black and red sushi oke. It appears to be made of a plastic-like material. It weighs about 500g, so it's sturdy and not easily breakable. Diameter: Approximately 32.5 cm Inner rim diameter: Approximately 30 cm Height: 7.5 cm I used it a few times to make chirashi-zushi (scattered sushi), but I no longer have a use for it, so I've been storing it. Please understand that this is a used item and may have scratches. If I don't have a cardboard box that fits the size, I will wrap it in bubble wrap for shipping. I'm offering it to anyone who needs it.
