TODAYFUL Hoop Earrings Silver (Pair) Outer diameter: approximately 2.8cm. These are medium-sized hoop earrings with a simple and sophisticated design, making a statement. Please refer to photo 8 for small scratches. These are not new and have been used, so they will be shipped after being disinfected. The silver may turn black due to air transport. In that case, polishing with silver polish should restore the original silver color. I have personally experienced this before. We do not accept returns or refunds even if the silver turns black due to air transport. Please purchase only if you agree to the above. If you have any questions, please feel free to ask.
