Since they are made by pouring enamel into the grooves of a metal mold, you’ll notice dips between the metal lines on the pin. Enamel can be any color or color combination you can imagine. In this mockup, the pins are shown in 7 types - black, bronze, steel, chrome, copper, gold and silver metals. Soft enamel pins are the most traditional type of pins. This is a mockup (imitation) of a soft enamel badge.
