This is a set of two items: ring earrings with balls and simple earrings. They are not sold separately. The price reflects the condition of the items. Material: Unknown Size: Large: Approximately 3.2cm in diameter, Small: Approximately 1.6cm in diameter The large ring earrings with balls have screw-on balls that can be removed. The threads on the larger ball side are worn, making the screw-on ball easy to come off. Also, the small ball on the ring earring with balls appears to be a regular small bolt that has been modified to be removable, rather than the original ball. The 1.6cm small earrings do not have removable balls and are the type that clip onto the ear. Please check the photos. Please purchase only if you are satisfied with the condition. If you have any questions, please comment before purchasing.
