Thanks #tryitsampling for sending me  Progressive International  Pre-workout  Prokeeper 6 piece  Food storage set. These containers came in really handy. I decided to use them for sugar, flour, coffee and little containers of creamer. Since using them, my sugar, flour and coffee have stayed as fresh as they were when first opened. The seals on the thing work great at keeping moisture out and freshness in. They are slim enough to fit together well in the cabinet. The different sizes gave me the chance to decide what I wanted to store in them. There are many types of baking goods or foods you can store in them. They are by far the best storage containers I have tried.
