Need a lunch box for DD2 that will last more than a couple of weeks!

[Tortoise]

Where can i get a decent lunch box from for DD2? I have the bag ones because they are a nightmare to clean and always split inside! Plastic ones are hard to find and the one she had has split so i need to find her a new one!

I have 2 Marks and Spencers bag lunch boxes (red and black) for DS. You can buy them for few quid but also get them free when buying three of the childrens meals. They come with a metal drinks bottle. I put them on a 60 wash with my tea towels on regular basis and they are still going strong!...watch them fall apart now I've said that!
