This is a very functional wallet, for a man it fits in the sport jacket vest pocket, holds currency in an unfolded state should you desire to carry large amounts of currency which therefore require you not to fold it to prevent a huge bulk.  The snap is a great idea, the metal in the wallet is minimal and should not set off metal detectors in airport.  The only thing I was disappointed was that the wallet was not made from leather or a longer lasting materical...patent leather is not a long lasting material in general.
