The Collie Tag is built of German silver with an antiqued finish. The standard size is 1.5"x1.5". If you prefer a different size be sure to let us know in the notes on the order form. All of our tags are hand-engraved. You will be able to tell with the finished product! This tag does not have stones included. If you would like to add a stone let us know. After you place your order, we will create a design proof and send it to your email to confirm before we begin on the tag.
