This is a collaboration necklace between U-TREASURE and Touken Ranbu, featuring a model of Kasen Kanesada. It has a refined and lovely design with pink gold plating on silver 925 and a pink tourmaline. I used it a few times and then stored it in an accessory case. There are no noticeable scratches or stains on the necklace itself. I will include the original box, but the box has some discoloration like sunburning (see image 7).
