About a year ago I purchased Debbie Meyer green boxes from HSN. This is a 20 piece set of food containers made of a durable plastic that really does keep food fresh for much longer than if stored in other ways.
These containers are dishwasher safe (top rack), microwave safe, and have tightly fitting lids that keep air out. The containers I have pictured are the large boxes for holding a loaf of bread.
I was really amazed at how well these containers work. They are very strong and are easy to clean, just wash with cool water and air dry. Before I purchased these food storage containers, I had to throw food out numerous times because it spoiled before it was eaten. I hate wasting food. So when I saw these containers advertised on HSN, I decided to give them a try, and I am really glad I did. You can check them out on the HSN website and find out all the pertinent information about them, but believe me, they do work.
If you are tired of having food spoil quickly, try Debbie Meyer Green Boxes. I think you will really like them.
