Seriously - throw out all of your P.O.S "snap & seal" containers and go to Wal-Mart/Target/any store that sells groceries and pick up a few of these bad boys in all 3 sizes! These Tupperware replacements are AWESOME!1. They don't warp in the dishwasher
2. The locking lids ACTUALLY stay on
3. They come in 3 perfectly practical sizes
4. They're stackable
5. They have marks for measuring
6. They have a textured, indented bottom for easy handling and no slipping around your fridge/freezer/countertop
7. They are DISHWASHER, MICROWAVE & FREEZER SAFE!
I have never loved a kitchen product this much! And I'm pretty disappointed in Ziploc and like companies for taking so stinking long to come out with something that completely ROCKS and is super cheap! For how long these babies will last - I'd say they are worth their weight in gold!
