I've used it a few times, but it wasn't quite what I needed, so I'm selling it. Since it's used, please understand that there may be minor scratches. The following is a quote from the store: 【Can be carried upright】 Commuting and school bags are full of luggage! The Foodman is a "thin lunch box that can be carried upright" that fits neatly into such bags. It's 210mm, the same as the short side of A4 paper, so it fits neatly even when carried with documents. You don't need to carry a separate lunch tote, so your luggage won't increase, making your commute more comfortable! 【Leak-resistant】 Prevents leaks with an integrated packing and 4-point lock! The W-sealing structure, which seals the perimeter of the main body and the dividers, prevents leaks. It also prevents the transfer of liquids between each space, preventing the transfer of flavors from side dishes, etc. *This product is not a sealed container, so do not put in items with a lot of water or liquids. This may cause leaks. 【Easy to clean】 The rounded corners have no "corners" where dirt tends to accumulate, making washing easy. It is also dishwasher safe, making it ideal for everyday use. *When using a dishwasher, do not place it near the steam, hot air, or hot water outlets. This may cause deformation or damage. 【Lunch plate feel】 Because it's thin, you can enjoy your meal like a lunch plate rather than a lunch box. The inside is off-white, which makes the colors of the food stand out, making your lunch look more delicious. 【400ml for minimalists】 The Foodman 400ml is the same size as a long wallet. It fits neatly into small bags. It's a minimal size, perfect for women and those on a diet. It's also a recommended size for those who only bring side dishes and want to add a convenience store rice ball or soup depending on their mood.
