I've google'd my brains out for the last hour, and I cannot find a film canister/container/box/whatever that holds rolls in bulk (5 or 6 rolls) and is preferably waterproof. Nothing for 120 either.
Only things I have found are some black 120 tubes, but they are for just a single roll.
Anybody know where/who sells something like what I'm looking for? I know I've seen them before.
