I found this while cleaning out my parents' house. It sparkles and reflects light beautifully. I think it can be used for formal occasions. It's earrings, so it's perfect for those who don't like piercings! The box is not included. I'm sorry, I don't know the material. I don't think there are any noticeable stains or cracks, but it has been stored at home. Please refrain from purchasing if you are concerned about minor details. Also, please check the images carefully before purchasing. I will send it off with care. Thank you very much ❀ #FormalEarrings #ShowaRetro #TaishoRetro
