Umm...I flipped my lid when I found these. They are old school "Best Friends" tags intended for your favorite furry friend! My pup Jolene and I rock our brass tags every single day. I wear mine on a necklace, but you could attach it to your keychain, split them between your pets if you have two, you could give the other half to your pet's best friend...the options are limitless! The charms are made out of Navy grade brass and develop a dope patina over time. These charms are made to be worn, used and loved and are sure to stand the test of time --- just like the love you feel for your bestie!
