I just picked up one of these neat little
Tight Pac containers off of eBay and I'm pretty impressed. It's a sturdy plastic lozenge/capsule 4.5" x 1.5" x 1". They claim it's "smell-proof" and seems like it will be pretty water-resistant. It also seems like it will be crushproof short of a real disaster. Mine is blue; they have them in several colors but unfortunately not red or orange. Should be pretty neat for storing fire gear or other assorted survival stuff.
The downside? They make some containers that won awards from "High Times" magazine and seem to have been designed to store weed!
But hey, it's just an empty plastic container!
