This is the lowest price, so please proceed with your purchase. I purchased this from the official store and used it for a short time on the day of purchase. It has been stored at home ever since. This is an authentic product purchased from the official shop. The original metal chain for the charm was accidentally lost while it was stored separately, so a replacement chain has been attached (see photo 7). The appearance and feel are the same as the original, but please refrain from purchasing if you are concerned.
