Thank you for viewing. This necklace was purchased over 10 years ago at the CHANEL Omotesando store. It is a used item, but before listing it, I had it maintained by the Ginza CHANEL Leather Atelier. Although there is no proof of purchase, the maintenance receipt from the Ginza CHANEL Leather Atelier can serve as proof. (They do not perform maintenance on counterfeit items) As shown in image 4, there is some rust-like discoloration on the back. Please be aware of this before purchasing. Included accessories are the box, dust bag, and maintenance receipt. In recent years, the sale of simple CC logo necklaces like this has decreased, making it a valuable item♡ Accessories: Box, Certificate of Authenticity
