Enamel Pins UFO Desert

I'm getting rid of part of my pins collection. All currently listed pins are gently used. This pertains to ALL of my pins currently listed. I've been collecting for years so these are from all over the place. Some backings may not match, but all fit. Placing these on cards is not an attempt to re-market/sell/brand them. None are my designs. Many are thrifted, many are from poshmark, and some were purchased new.
