Soft enamel pins are created by adding the enamel only once in the recessed areas of the metal and then baked hard. The enamel is below the metal edges, so when you touch the pin, you get a textured feel.

Soft pins are the most popular types of pins because they are versatile (lot of choices in shapes and sizes), of medium quality and cost-effective.

Hard enamel pins are created by pouring enamel several times in the recessed areas of the metal and is heated at very high temperatures. It is then polished smooth to ensure that the enamel is at the same level as the metal edges.

These are high-quality, premium looking pins and are also very durable.

Epoxy is a transparent resin that is added on the surface of the pins to make them smooth and bright like glass. Epoxy adds a protective layer on pins and prevents them from oxidization and staining.

Epoxy pins are great for printing complex designs, have a unique 3D effect, and are durable.
