These hoop earrings are made with materials that are less likely to cause allergic reactions. They have titanium posts and are coated with 18k gold. I purchased them new for 1,980 yen and used them for about a month, but I am selling them because I bought different earrings. The design is simple and easy to wear. They are also made in Japan, which provides peace of mind. There is a small scratch or peeling on the inside of one of the hoops. The post seems to be slightly bent. (You can see it slightly bent from the side in the 10th photo.) Also, the catch was originally a little loose. I have wiped them with disinfectant. I hope that those who understand that these are used items will consider purchasing them. Thank you very much.
