I'm selling this because I opened the package, but it wasn't what I expected. It has never been used. This is a tight lunch box with a dome-shaped lid that allows for fluffy arrangements. It prevents things like nori seaweed from sticking to the lid and prevents food from being crushed. It comes with a high divider to prevent side dishes from shifting. Dishwasher safe and microwave safe (remove the lid). Includes a name sticker. 【Product Size (approx.)】 Size: Width 131 x Depth 114 x Height 55mm Capacity: 270ml *This does not inhibit the growth of all bacteria. *When putting in hot food, let it cool down before closing the lid. ● Made in Japan
