I Purchased the oxo storage containers from Wayfair, purchased two more for wedding presents. One of my favorite things. Now these are wonderful! Perfect for any box of cereal. Open your cereal,  close the lid, containers have a push button that opens the lid and pour .  Easy enough that any child can do it by themselves. They are airtight and keep your cereal fresh for weeks. No more opening boxes and rolling the plastic down to try to keep the cereal fresh!
