I like the kind that are like an actual bag that closes with velcro. Fewer things to go wrong. That's what DD and I use.
However, I got DS one from Land's End that matches his backpack, and it held up very well. It looks like a miniature backpack with zipper all around it.
Re: Good quality lunch boxes?
GoGreen lunch boxes. Each of my girls has one. LOVE LOVE LOVE them!

And I realize that they are pricey (I got them for $20 each on one of the discount sites), but they are worth the money.
