Thank you for viewing! This is a set of a necklace and earrings. The earring posts and catches are K18 (stamped). Although it may look like there are uneven paint spots, this is how it was originally and not due to any damage from use. I used it 2-3 times and then stored it carefully for a long time. I think you can use them stylishly as a set or individually. I would appreciate it if you would consider purchasing, understanding that this is a used item. Thank you very much.
