Fully functional to fit any standard bottle cap, our Bottle Opener Dog Tags are custom molded to fit your own exclusive logo or design. They are die cast in zinc alloy and are 2mm thick, so even the most stubborn of bottle caps won't stand a chance against our dog tag bottle openers! We offer a variety of antiqued or polished finishes to make your design stand out, and they come with 30" neck chains or split rings. Add color enamels, matched using the Pantone Matching System, to really make your artwork pop. A great choice for parties, promotional events and more!
