The lid for this Bento Box stays on so well! It is snug and secure and completely waterproof! The four hinges, one on each side, ensure the lid is on and on to stay! I love that. If you drop it, nothing will come out or leak. This is especially good for kids since their lunches go through so much on the way to school and the lunchroom! No soggy backpacks or clothes from a leaky lunch!
The box is sturdy and can deal with being put in the microwave and the freezer. You do want to take the lid off though to heat it in the microwave so you do not damage the seal! Foods that need to be kept cold can be popped in the freezer and then have all morning long to thaw and still be cold and fresh for lunch!
This is a great bento box and with it's low profile will fit in backpacks, briefcases and more to save space and still give you a good sized lunch.
