These are great! I'm using the middle size to put dry cat food in. The big bags from the store are too heavy for me. These are great storage containers for any type of food. They are easy to to use, the tops come off pretty easy and go back on the same way. But they are on with a air tight seal. 

Pros: These were a great value. They are very easy to hold and pour. Super great quality.
Cons: none
