Our signature key fobs are a combination of Veg Tan leather, and antique brass hardware.  The leather will form a beautiful patina over time and turn to a rich tan color.  Use the attached hook to hang your keys in any location both at home and on your gear.  Hang those keys on the outside of your pocket and not burried at the bottom.  Do you keep your cell phone in a pants pocket?  Why risk scratching that screen or damaging the camara lens?  Keep those keys hooked in a safe spot.
