Hi Guys

Thought I'd just pick your brains. We are looking for a box or bag designed to carry iPad's about without them getting smashed and trashed. The box is only needed for the staff/students to carry the iPad's between classrooms and the iPad charging trolley.
Does anyone have any recommendations? I have come across these TheCaseProject: Multi IPAD cases but they look on the expensive side and a little overkill as we don't need the charging feature, though the foam inserts do look like the kind of thing I am looking for. Alternatively, does anyone have any ideas on how easy it is to get custom foam inserts made for a regular plastic storage tub?

I'd be curios to see how you've gone about solving this problem in your establishments, too.

Cheers for any input.
