Promising review: "I cannot believe how much I love these containers. Believe it or not, this keeps my lettuce fresh, much longer than in a plastic bag or factory packaging. I used to constantly throw lettuce away because some would spoil before I got to it. Not a problem anymore! I also decided I wanted to keep a salad bar of sorts in the fridge, with all the veggies and toppings pre-chopped so all my family has to do is put it together and get some dressing. I thought for sure there is no way I can cut up things like cucumber and tomato and have them not get nasty (because I've tried before in regular Tupperware type containers) but amazingly enough it works. I have a chopped onion that's been in there for like two weeks now and it's still fine (I'm the only one that uses onion on my salad). So far all I've tested is tomatoes, cucumbers, and onions as well as regular lettuce and spinach kale. They work amazing for all of it." —Kristina
