This double wall food container and its three practical parts let you carry your whole snack or meal together. As a matter of fact, it can be used as much for soup and crackers as for milk and cookies. The lid doubles as a bowl to eat from or as a cup to drink from. The mid section can be used as a snack container. The bottom container is double wall to keep your food or beverage at the right temperature and if you ever need to heat its contents, you can even put the container in the microwave. You'll be happy to learn that it has a lifetime warranty and is BPA free. It is also an original Trudeau design.
