This Medical ID Capsule Pendant is a secure way to have important medical information at all times. Medical bracelets have long been a way to make allergies, medication or illnesses visible to an emergency responder, but not everyone likes to display this all the time, or likes the look of a bracelet. This capsule pendant that includes a steel insert can be worn visibly or under the shirt. There is a rubber seal around the screw-on top and bottom half that will keep it tightly fastened until it needs to be opened. It includes your choice of 18, 20 or 24 inch chain.
