These solid brass or copper tags are each a unique, diminutive bit of art. But more importantly, they will get your dog home faster than a microchip. One of my dogs was wearing his tag when I got a phone call while at a doctor appointment. The tag got Maxwell found before I even knew he was missing!  
The tags are made of solid brass or copper, hand engraved, chemically etched them polished to a bright finish. The nonferrous metals can be maintained by polishing at home to keep them bright but they also tarnish to a georgeous, natural patina. If desired, I can ship the tag to you already patinated (think of the Statue of Liberty).
