Prestige looks at a popular price. A popular choice for sports clubs, soft enamel is a durable, high quality pin that lends itself to enhancements such as spinners, blinkers and danglers. Itâs perfect for simple yet bold designs, with separate areas of bright color.
Plating is the next step in the process. For this type of pin, the most common plating types are gold, nickel (silver), copper, and black nickel (dark silver/black chrome). These raised metal surfaces are polished to a mirror finish, while recessed metal areas are filled with an enamel paint.
