The snack one that I got is great for putting little snacks in and throwing in Caitlyns diaper bag. The divider allows you to pack 2 snacks and the container is really sturdy.
Would I go out and buy the lunch ones for the boys lunches? No for 2 reasons. One, the Ziploc ones are doing a good enough job and Two, I did not have enough time and creativity to put together a fun, exciting, new and different lunch together every day. Am I bad mother because of this? No, just a normal one that works and has a left brain (not much artsy fartsy stuff in there, mor math and logic).
Also the price was kinda high for me. Some people justify it because it will last forever, no plastic at all, and they are sturdy.
If you are the crunchy type or think they would be a great beginning to the bento adventure go out and buy these. They are really nice and for a aluminum container the price is right.
