Excellent for making necklaces, pendants, or pins out of them.. just add some designed paper behind it and instant necklace.
...the different shaped tab makes them very unique... beautiful old patina !! these are perfect for a jump ring, bail,or some just wrap colored wire around the base of the tab.. . some may have discoloration on the frame, which adds to the patina some might have blemish or small scratch... after all they are vintage lenses.. and have been used for years.. in need of a good cleaning job..
