A sushi box is a type of container used to hold and serve sushi. It is typically a rectangular or square-shaped box made of plastic or cardboard, and it usually has a clear lid so that the sushi inside can be easily seen. Sushi boxes are commonly used in sushi restaurants, takeout places, and supermarkets where pre-made sushi is sold. The sushi is usually arranged neatly inside the box, with each piece of sushi placed on a bed of rice and garnished with various toppings such as fish, vegetables, and sauces. Sushi boxes can be purchased pre-made, or they can be assembled at home using sushi-making kits.
