Cubeware Rectangular Black Reusable Plastic Microwavable Food Container with Clear Lid Set, 16 Ounce - 150 Set per case.

Very disappointed when we started to use these in that the lids do not lock on, at all.We bought these because a local grocery store uses this brand and model number in their deli, and the ones we got from there have lids that snap on, lock and stay in place. The case we received, the lids barely stay on--if you touch them, they'll come loose or fall off.Would not have ordered these if we'd known we weren't getting the exact item that is offered commercially.

We enjoy dividing all of our left-overs into these container and freezing them instead of putting them in large tupperware and throwing them out at the end of the week. We use stickers and write names on them and then send them with the kids to school and take them with us to the office. Very easy to transport and hold up pretty well, just don't drop them right out of the freezer or they'll crack.
