Hard Enamel

Hard enamel pins (or “Cloisonné” pins) have a smoother, glass like surface. Hard enamel is very durable and is less prone to scratching. When a hard enamel pin is made, the process is similar to a soft enamel pin where color is filled between the recessed areas of the pin. After this process the pin is then sanded to create the smoother finish.

Limited Edition

If a pin is marked as a limited edition, the maker does not intend to produce additional runs of the pin after the initial run has sold. This makes the pin more rare and harder to collect. Sometimes a variant of the pin may be created to allow for additional sales while keeping the original limited.

Locking Fastener

A locking version of a clutch that contains an additional bolt that can be tightened to further secure the faster to the post with a small allen hex key. Locking fasteners are usually bigger in size, but help keep the lapel pin in place.
