Jewelry quality, exceptional color and shine, and a high perceived value. Epola Cloisonne lapel pins are at the top of the food chain in the custom lapel pin industry, with a smooth glass finish and rich, deep colors. We start with a solid copper base casting that is thick as a quarter. Colored enamel is placed accordingly in the valleys to develop the image. Then a glass bead powder is placed into the recessed areas of the pin until flush and fired at 1600 degrees. The custom pins are then plated in a high polished gold, silver, or black metal nickel and polished until smooth.
