Getting ready for back to school shopping and lunch stuff has always been a problem. We finally found water bottles that don't leak and fit well in lunchboxes (14 oz Pogo from Target) but now we need something for food. It needs to be leak proof and fit in a standard kid sized lunchbox. The lunchboxes get dropped into a laundry basket once they get to school and then the basket is dug through at lunch time so they definitely don't sit flat.
