Does such a beast exist? I pack my lunch daily and must heat it in a microwave in the container that I brought it in. I currently use pyrex and the reports on exploding have me concerned. I've not experienced this problem, thank goodness, but I've got another, more immediate problem. The little blue lids that came with the bowls no longer keep their seal so well and are beginning to leak. Nothing like finding a little soup in your purse!
Any suggestions are welcome. I really need a permanent solution; I don't want to have to replace again in a year or so.
