I won two battlefoam trays at a store competition. They work great for holding my stuff, but I haven't got it figured out very well how go transport them properly. I've got them smooshed into a bag sideways,which works okay until it doesn't, and then all my stuff tumbles out into a big heap. This is how I ended up running over my defender.

I've got a plano box for the stuff that doesn't fit in the trays.

What can I do for the foam? I see there are proper bags to hold them, but I don't want to spring for one when I've got perfectly good tape and old cardboard boxes laying around. I don't really care what it looks like. Does this sound doable?

Anybody else have experience with doing something like this? Is there some other kind of thing that is cheap I could fit them into to prevent my stuff from spilling out?

Thanks for any help
