I love, love, LOVE these containers. The fact that I don't have to pull out a machine to get vacuum seal is GREAT for me! I've stored rice cakes, nuts, spaghetti, etc and nothing so far has been stale.
These are made with very thick plastic which would take a lot to break. They are easy to open and close, even my kids can use them. And they also LOOK great in my pantry! I love that the containers are see through so I can see exactly what I have at any given time. Definitely 2 thumbs up and 5 stars from me!
