It's important parents understand this. The packaging for dry flower, albeit wasteful, tells us:
If your kid eats your bud, it's literally going to be 100x less powerful. They'll be tired, maybe hungry, but nowhere near high.
>childproof packaging for [insert any object]
Can't beat versatility though! :D
I have a small fire-resistant lockbox that I keep a backup Yubikey, flash drive, and a few important documents in.
If someone's really intent on getting in to it, they can. But having pulled one of these out of a house that burned down, they're awfully handy if you need to get to insurance and financial accounts sooner than you can get to a safety deposit box at a bank.
But if you're just looking to hide it, there are lots of stash cans that will work. I like this one, because the packaging of the actual product doesn't change often, and nobody will accidentally grab a can of tire foam from my garage the same way someone might with a soda can hidden in the refrigerator.
