This is a bamboo box that contained rolled sushi, a souvenir from a high-end sushi restaurant where a meal costs over 50,000 yen per person. This item will be shipped as a set of 3 boxes. The rolled sushi was wrapped in plastic wrap, so nothing was on the inside of the lunch box. I dried and stored them in a clean condition. I am selling them because I have too many. The rubber bands to secure the box are also included. I have used similar boxes to hold onigiri (rice balls), sandwiches, and snacks. This is a bamboo lunch box. It is made with traditional bamboo craftsmanship. It is well-ventilated, which prevents the rice from getting soggy. It is durable and can be used repeatedly. With its Japanese design, it is suitable for picnics and everyday use.
