Yep!

Mine has survived a few mishaps, including having my ammo box with about 300 12 gauge shells dropped on it, thrown off a speeding 4 wheeler, and generally tossed about carelessly.

I do have an extra sheet of thin foam that i put in there with my smokes, since it seems only 50rg or larger actually stay put.

what count model did you test? I have 3 of the five count boxes, and I'm thinking of moving up to a 15 or bigger.

oh yeah... hope the kidneys feel better
