Vintage Gold Tone Hoops Stamped OTC BRZ Italy

Excellent condition they were in a little bag so unsure if they were ever worn- i’m sure they were at one point but look about perfect Beautiful gold tone vintage hoop earrings with snap close It took me forever but i finally was able to make out the stamp it says OTC BRZ and Italy on the other side. Pretty small added a pic next to cotton ball for reference (only thing i had on hand 😂)
