The
TMT Tactical Wallet has a watertight seal to protect the multiple secret compartments on the inside. On the outside it has a toothpick, tweezers, compass, glass breaker, and--no I'm not kidding--a combat striking edge. The wallet itself is made of RFID blocking material so bad guys can't get your info that way.
It's like having a ninja in your pocket, except it doesn't get its ass kicked by pirates every 5 minutes.
