Thought I'd pass this niffty little find along. You know how you can never have enough water tight storage boxes in the bus, well I stumbled across this one by accident.
We bought them for what was inside the box, not knowing that the box was worth more. I filled it with water to see if it would leak and it didn't. I now have a very handy storage box with more being added monthly.
PS...You can get your very own, identical to mine at Sams Club
