The box can be taken apart into three parts, a bottom part, the rectangular walls, and a top part. Before use, the box should be put in water so that the rice sticks less to the box. The bottom part and the top part can be covered with a layer of plastic foil for easier cleaning. The bottom part and the walls are assembled before the rice and the topping is added. Next, the top part is used to press onto the sushi, hence the name pressed sushi. For disassembly, the rectangular walls are pulled up while the top part still presses onto the sushi. After removing the top part the sushi is cut and can be served.
