Well need some inputs from you all! I've got a daughter that loves to pack her lunch however she is not very neat in a hurry, throwing everything in the insulated bag and by the time she gets it home, opening the bag leaves a mess and smelly to boot. I did try to wash it but it was a failure because nothing inside would dry out and stinks. I won't be buying those insulated bags anymore (canvas outside layer). She loves Hello Kitty but now into other things. I often wondered if Tupperware or similiar lunch boxes would suffice. I used to remember having those tin boxes, old thermos (be careful if you drop it, it would shatter) and some schools outlaw it for their own ridiculous reasons (as a weapon, even a pencil is a weapon too!). Those tin boxes are making a comeback but not too useful in washing it out because the hinges can rust. Unless any of you don't have any problems with it. I will NOT buy insulated bags that made of the same material as backpacks. Handy they are but not good for real messy jobs. Dirties easily too! What do you all like? DD is seven and going into second grade this year.
