I kept the necklace for months, I wore it every day... I even showered with it on!! I honestly could not think about giving the key away! But that changed when my mother got into a car accident, leaving her with severe injuries that could have been fatal. She was in the hospital for what seemed like forever. I gave it to her right before a surgery. She told me how it helped, how encouraging it was. These keys are amazing and such an inspiration.
