My eldest is starting year seven next month, and a lunchbox is pretty much the last bit of shopping we need to do. Everything I see is aimed either at primary aged children (with Disney prints etc) or adult office workers (much too big to carry around in a school bag all day).
I've found a Thermos one which is pretty good, but is an incredibly boring plain blue.
Where do you get insulated lunch boxes/bags from that are small enough for a tweenage lunch preferably with a vaguely interesting pattern, but don't look too childish?
