I was a bit skeptical at first.  I was afraid that the cover wouldn’t seal properly and that the cereal would become stale, but absolutely not!  Cereal is always fresh like we just opened the box and the cover for these are nice and seal very well.  The only thing is that you have to make sure that you align everything correctly because if you don’t then it is a bit difficult to secure the tabs on the covers to the container.  I like that it’s clear so you can see everything inside and it holds a lot of cereal too.  I usually purchase in bulk so a large bag of cereal would fit into one of these with no issue.  It is nice and light when empty and very easy to clean.
