Vintage Screw Back Earrings Brown Natural Vibes Boho - Condition Issues

Vintage Screw Back Earrings Brown Natural Vibes Boho - Condition Issues These earrings measure about 0.75". Not sure what the material is. Design differs between the two. Quite brittle/fragile. Some sections have broken off each earring. Plastic screw backs have discolored with age. Some glue visible to rear. Preowned vintage earrings, sold as shown - I am unsure of material type(s) because of this. Pictures show different angles for you to review - while I attempt to note any defects, some tarnish/signs of wear may be visible that are not otherwise stated. Earrings are tested and photographed on a thin/smooth earring stand (not included) to show that the clips are in working order. If you have any questions please feel free to drop me a message.
