When there's an emergency, you may not be able to speak for yourself. Keep this life-saving packet on your refrigerator where emergency medical personnel can easily find it. It lists medical information, emergency contact info, even a section for pets that could need attention if you're hospitalized. It will be easily visible and there to help with access to important information you may not be able to give. Emergency medical personnel are there to help you and the more information they have available right away could help save your life. The magnet on the back makes it able to firmly stick to any metal surface but we recommend the refrigerator because many first responders are trained to look there in an emergency. 4 ¾"x8".
