Stainless steel food container

This is an awesome container. It will keep your food hot or cold. It comes with a divider so if you want you can put two different foods in it. It is very durable and a beautiful piece of dish ware . It has four lock downs on it which is great and if you put hot food in it , it also has a red button for you to push to let the steam out so you don’t accidentally get a steam burn and that is one great feature to have.

Love it

I bought it as a lunch box for both my child and myself, and it's really great. The food stays warm very well thanks to its excellent insulation and good sealing so no leaking! It's also very convenient since my child can easily open and close it. I'm really happy to finally have purchased a properly insulated lunch box.

Great container

This Mainstays 33oz rectangular insulated food container does a great job of keeping food warm or cold for a decent amount of time. The size is perfect for meals on the go, and the lid seals tightly to prevent leaks. The material feels durable, and it's easy to clean. A solid choice for anyone looking for a reliable food container.
