Round silver rings with a white ribbon dangling in the center and the words "Bone Cancer Awareness" all around it make up these silver horseshoe-shaped keychains for bone cancer awareness. A great item to offer to raise money for bone cancer programs and initiatives. The charms have a diameter of around 3/4 inches, while the sterling silver-plated keychains have a diameter of almost 1 1/2 inches. Each keychain comes in its own bag.
