I ordered a handful of these containers. Now, I'm wishing I would have ordered dozens more! They are perfect for taking lunches to work. I haven't filled them full of liquid - mostly pastas, meats, dessert - but haven't had any issues with leaks like the other reviewer mentioned. They stack nicely in the fridge or freezer, and are perfect for freezing leftovers for "frozen dinners/lunches". I even put making tape with the contents on the side so I can easily tell what's inside when I freeze them.
