Natural wood circular sushi oke (tub), approximately 30cm in diameter, with a simple design, perfect for arranging sushi. - Material: Wood - Color: Natural Wood - Shape: Circular - Use: For arranging sushi - Size: Approximately 30cm in diameter - Design: Simple design The band that looks like copper doesn't seem to be metal, so it should be easy to handle. This is a new, unused item, but it is made of natural wood and has what appear to be stains. Please understand this. I have taken pictures of the areas of concern, so please take a look. 30cm is suitable for small families. Those who use it for somen noodles, etc., may find it suitable even for large families. Thank you for viewing.
