Dog tag blanks provide you with a classic metal shape for making jewelry pendants. Choose from brass, copper, aluminum, and 304 stainless steel. All options have rounded corners, and some have rolled edges. All metals can be used with paints, inks, glues, collage, decoupage, and image tranfers. Aluminum, brass and copper can also be hole punched, metal stamped, embossed, soldered, riveted, and engraved. (Stainless steel is a hard metal and is not recommended for stamping, embossing, or punching holes for riveting).
