This RunJunkEes® aluminum shoe tag, made by designer Hailey Howell of BearNBabes, is hand stamped one letter at a time and also has our familiar little running buddy. The charm measures 5/8 x 1 15/16 inches. Makes a great giftAluminum is a fabulous lightweight metal that is hypoallergenic and does not tarnish!Handstamping involves striking metal with steel stamps by hand to create letters, words and designs. Each letter will probably not be straight or even or the same depth as the other letters. This is much deeper than engraving and therefore, there will probably be a slight impression on the other side. None of this is a defect and lends itself to the unique, one of a kind piece that will arrive in your mailbox as no two pieces are ever exactly the same!
