I have never seen any real reason to own a bread box, just keep your bread properly sealed in the bag and you shouldn't have too many problems. If some goes stale, well then you have something to feed the birds. Do bread boxes even keep bread fresh? Who knows, who cares... but, I have completely changed my mind and I have to own an Armadillo Bread Bin. It vaguely resembles an armadillo, looks more akin to armor from medieval times, is the single coolest kitchen object you could ever own and it stores bread too! You don't need one, but come on, look at it, it's a total object of desire.
