"Dog tags" are identification tags that are fitted to every US Army soldier. The name, surname, blood type and some other information are then stamped on the stamps. More information can be found here on Wikipedia. Identification marks are used not only by the US Army, but almost all armies, the Czech Army or Bundeswehr as well.
If you are interested in your own custom dog tag or want to please your loved ones with an original gift, you can easily order a custom stamping on our e-shop. We will also produce personal dog tags for you at our store in Prague 9. At Armed, we also offer original stainless steel chains or rubber stamps that prevent the clinking of metal tags on themselves.
