I purchased this new from a store called Excel World on Rakuten Ichiba about 15 years ago and wore it almost every day. It has deteriorated over time, and it broke a few years ago. I had it repaired at a local jewelry store, but it broke again recently, so I've decided to wear a different necklace and have kept this one without repairing it. Someone once purchased this, but the transaction was canceled after the following assessment by the "Assured Appraisal Service": Therefore, the Assured Appraisal Service cannot be used. 《Appraisal Result》 ・Appraisal Failed 《Reason for Appraisal Failure》 ・This product has many sophisticated counterfeit versions circulating, so it was necessary to pass special criteria established by the appraisal service. However, it was observed that certain parts had individual characteristics that made determination very difficult, and we were unable to provide a definitive appraisal result, resulting in a failure to pass the appraisal. We appreciate your understanding. I am confident that this is a genuine product, as I purchased it from a reputable shop with a long history of handling branded goods. I hope that someone who understands the above will purchase it. 【Material】Silver 925 【Size】20 inches / Approximately 50cm (Men's standard size) Chain...Roll chain Accessories...None Scratches/Discoloration...Yes
