The engraving and chain are in incredibly clean condition, as shown in the photos! I don't think you'll find one in this condition very often! Thank you for viewing. LOUIS VUITTON LV Monogram Necklace Nanogram Two-Tone Bi-Color Total length: Approximately 46 cm Product number: M68074 Accessories: Simple wrapping only The serial number, product number engraving, and LOUIS VUITTON engraving can all be confirmed. I will add more images if needed! Purchased at the Seibu Department Store in Shibuya. I discarded the receipts as I didn't intend to sell it, but I believe you can tell it's authentic from the photos. However, if you still have concerns about authenticity, feel free to comment, and please purchase only after you are satisfied. It has been professionally cleaned, and there is no peeling of the plating! The condition is good, and although the photos taken with my phone aren't perfect, I've taken many, so I think you can confirm the condition. I haven't done any editing, so please rest assured. Please note that there may be some minor scratches from storage. It was expensive when I bought it, so it will be a high price among my listings, but I will pack it carefully and ship it.
