Soft enamel metal pins
Soft enamel pins are a strong default for custom metal pins because they balance price, color and detail. The raised metal lines protect recessed enamel areas and create a tactile surface.
Hard enamel lapel pins
Hard enamel is polished flat after color filling. It is common for premium metal lapel pins, corporate gifts and retail pins where a smooth surface matters.
Die struck metal pins
Die struck pins use metal relief without enamel. Antique plating makes the design visible and gives the pin a traditional coin-like finish.
Zinc alloy, brass and iron
Zinc alloy suits larger or complex shapes. Brass gives sharper stamped detail and a premium feel. Iron is efficient for many standard enamel pin badge orders.
