I’ve seen metal snuff boxes in my local pound shop! Advertised as portable cigarette ash trays!
They won’t be any use for snuff because they won’t have anywhere near a snuff proof closure - they will either leak profusely or the snuff will be dry in a couple of hours. If they are advertised as ash trays its because they are - have a look at the buying snuff boxes thread to avoid waisting your money.
…you know…if they aren’t capable of holding snuff, what would make them capable of holding ashes?
I use smash boxes. They’re ace! And cheap.
I guess the volume would be less but for a pound you could always get one to find out
