I ordered this because one of my students brings their breakfast and lunch in every day and I noticed it never leaked we can put it right in the microwave to warm up their food instead of having to plate it.
My husband and I bring lunch every day and every day we have to think about what we are bringing. Soup, Salad with oil and vinegar and more. You can also put them in the oven as long as you take the lid off. The lid should NOT go into the oven or the microwave.
The set comes with 6 containers (2.3 cups, 2.7 cups, 3.4 cups, 4.5 cups, 4.7 cups and 6.4 cups)
They all have a four tab locking system which makes them completely air tight.
