Legend has it Evil Road Spirits have been latching themselves on to motorcycles for as long as there have been bikes on the road. These Evil Road Spirits are responsible for mechanical problems and bad luck along the journey. Legend goes on to say that by attaching a small bell on to your bike, the Evil Road Spirits will become trapped inside the bell where the constant ringing drives them insane, making them lose their grip and fall to the ground. Legend also has it that the mystery of the Guardian Bell carries twice as much power when it is purchased by a friend or loved ones and given as a gift. US Marines Guardian Bell is officially licensed designed with eagle, globe & anchor on front, and Semper Fi - Marines on back. Cast pewter design with split ring for installation on bike or keys. Includes black velour gift pouch. Dimensions: approx. 1.5" H X 1" W.
