Adult earrings that can be used all season. The exact purchase date is unknown, but it is believed to be a vintage item. There is no backing. I don't remember using them, but please understand that they have been stored by a private individual. The diamond-shaped part is about 2cm. *Please note that these are earrings, not pierced earrings. I will disinfect them before sending them to you. They will be packaged in a Uni-Pack bag.
