These POP containers are awesome. I already have a few and know how great they seal so naturally I was very excited to receive this one. So easy to seal, just press down on the button on the lid to seal closed or to open. This one is a nice sized 3.7-quart container that is enough to hold 4 boxes of spaghetti. These containers are stackable, which is definitely space saving in your pantry. Definitely recommend this great product from Oxo, and I'll be shopping for more!
