This dog tag-shaped bottle opener hearkens back to the history and use of military challenge coins, when those caught without their unit coin were compelled to buy a round for all their buddies. That spirit of camaraderie is captured in this boldly detailed and highly practical piece. The front features the U.S. Marine's mascot bulldog with the phrase "Devil Dogs" above. Beneath a rendering of the letters USMC, the reverse is imprinted with the motto "Semper Fidelis," a succinct statement lived out each day by all Marine personnel. Struck in a brass alloy and finished in antique bronze, this closed-loop bottle opener features a cut-out area approximately 1 1/4 inches in diameter.
