We can produce soft enamel lapel pins using iron, copper, bronze, zinc-alloy material. The copper material is more expensive than other kind of material, so for promotion gifts, we usually suggest to using iron material to make. This can save some material cost and the weight is less than copper material, also can save some delivery cost. The surface finish is almost the same with copper material, for big size pins, we can make them using zinc-alloy material, zinc -alloy material pins can with complex content and with 3D relief looking, this is also welcome by most client. The lead time of soft enamel lapel pins is shorter than other styles, that's why we can produce custom trading pins in 7days, and insure good quality.
