When the kids started kindergarten, we began the ritual of packing lunches, but were concerned about the cost, health aspects, and environmental problems with using little plastic sandwich bags. So we splurged (~$30) on a metal ‘bento box’ we found online.
We got the Three-in-one and we’ve used it every day (at least, every school day) since. It keeps food separate, which is not just for picky kids, but to keep damp food (baby carrots) from touching dry food (sandwich). It packs up compactly but holds enough food for a kid’s lunch.
It washes easily. We usually wipe it down at the end of the day and put in the dishwasher after every 3 or 4 uses.
The first time we used it, the metal clasps held the top on so tightly that our little one couldn’t open it. But we just bent the clasps slightly outward and now it has a snug fit but is also easily opened.
We though the kids would be excited about it, but they’re not. Just the parents are.
