Gordon,
That's true about bird nests, if you are lucky enough to find one to use or to save for later use. Also true about the 35mm film canisters, which I still have a few lying around. They are water-resistant, that much is true, but if they get side pressure exerted on them, the lid can (and oftentimes does) pop off. So, they are water resistant but quite fragile.
Back in the 70s and 80s when I was growing up, you could walk into a Sunny's Surplus and get a genuine U.S.G.I. Matchsafe for .50 cents and later on a buck. Great deal, threaded cap and very robust.
