I'm selling this because I don't use it. It's new and unused, but the bag has been opened to check the condition. Please be aware of this before purchasing. Please check the photos. This is a product from Skater Co., Ltd., a major domestic kitchenware company! This is a tight lunch box with a dome-shaped lid that allows you to arrange food in a fluffy way. It prevents nori (seaweed) from sticking to the lid and prevents food from being crushed. It comes with a high partition that prevents side dishes from shifting and a convenient inner container for separating food, allowing you to use it according to your needs.
