After returning from vacation, I pulled out the lettuce which had been in our refrigerator for three weeks thinking I would have to toss it out. I had stored it in one of my Lock 'n Lock containers and when I opened it, to my surprise the lettuce was crisp and fresh. I am sending a picture so you can see for yourself how effective these containers are. Just think of the money you will save by using these to store leftovers or bulk foods.
