Time Will Tell
This is a really cute lunch box. We use it only 2 days/week, and the original zipper broke after a couple of weeks. The top actually zips completely off, which I assume is to aid in personalization. I sort of expected that to be an issue at school. That his teachers would get annoyed at him taking it completely off. But so far that hasn't been the case. PersonalizationMall replaced the broken lunch box and we've been using the second one for a few months with relative success.
