I switched up using old shoe boxes and cigar boxes and the like to plastic shoe boxes that I can get at Walmart for 99 cents. The are more secure, more durable, and just the right size. I figure I've got maybe 40 or so of them now holding all sorts of gear, ammo, supplies, you name it.

Nothing beats a cheaper upgrade.
