I bought this to store my cat's treats in.  I was tired of fumbling with the zipper top packaging the treats come in.  The zipper top never seemed to close perfectly so I'd end up with stale treats which I'd have to throw out because my cat wouldn't eat them.  This Pyrex food storage container seals tightly ending the wasted treat problem.  And the 1-cup size almost holds 1 bag of treats perfectly.
