Resin Epola Lapel Pins This is our most popular style pins. Manufacturers refer to EPOLA as 'Misty' Cloisonné, Resin Cloisonné, Imitation Cloisonné, or Hard Enamel. Regardless of the Name, Resin EPOLA is the highest quality pin. Epola, is a Resin Based color powder, heated at 800 to 900 degrees, it creates a bright, smooth, Hard Enamel finish.  EPOLA pins are color matched using the PMS color chart, and thousands of colors are available. Soft Enamel Lapel Pins Soft enamel is not really soft. It may have a tendcy to chip, which is why we recommend epoxy as a protectant.Soft enamel can also be matched to the PMS color chart.
