While I haven't used them very often, there are some minor scratches and discoloration on the post. There are small scratches when magnified, but they are not very noticeable to the naked eye and are not the kind of scratches that would bother you when wearing them. The post has discolored. There are no problems with use, but please check the photos. These are very cute earrings with a flower motif and sparkling diamonds. They are K18. There is a box, but the shipping cost will be higher if the box is included. Therefore, I will send them without the box, wrapped in bubble wrap and using Yu-Packet Post Mini. If you would like the box, please let me know. The box has some minor stains.
