What will you hide in your $(removed) book safe?

If a burglar got their hands on this book safe ($(removed) on Amazon) disguised as a dictionary, they would have no trouble breaking it open on the spot. More likely, they'd just take it home and open it there. But if you stick it on a shelf with a lot of real books, and put a book cover on it, it's unlikely to be spotted. It comes with two keys and has a 2 x 5.625 x 9-inch storage area.
