Basically I am crazy obsessed with these food storage containers from OXO. They are amazing. Every time I go to Target or Bed, Bath, and Beyond I stop and seriously consider buying them if only they weren't so expensive. The lid has a push-button in the center and when it is pushed in the container will absolutely not open. Once the button is pushed out the lid easily comes off. No spending 10 minutes trying to get the container open. I love these so much. I think they are fun. I can not wait to have my own home so I can use these to store food.
