Our pet ID tags are all custom hand stamped metal tags personalized to your dog's name. Each tag comes with the option of a phone number stamped onto the back. We include a ring to attach to the collar. Since all of our tags are hand stamped, they are not always exactly perfect! We love them because they are each unique to every pet! Our tags do contain small pieces and can pose a choking hazard. We are not responsible for the misuse of our product.
