The N-Style ID gold plated stainless steel heart medical charm is one of my first designs. This medical caduceus charm may be ordered in either rose or yellow gold plated and comes with an attached lobster clasp making it easy to add to a bracelet or necklace. We will custom engrave it for you for free with diabetes, pacemaker, Alzheimer's, penicillin allergy or any other medical condition or allergy. This medical ID tag is 1" X 3/4".
