This pin is made of plastic PLA and painted with acrylic paint by me. I just love and miss the whimsy and fun vintage and antique jewelry had.  Some light imperfections due to the nature of it being handmade. Size in photos. Just a light dusting from time to time should keep them clean. Avoid cleaning with water. It's hard to see in photos, but they are a silky cherry color that acts kind of like moonglow lucite. Just to be safe, the glue used for the pin is E-6000. Please let me know if you have any questions. I'll be glad to help. Thank you so much for looking!
