I purchased this at Tower Records in Shibuya a few years ago. This is an official product. All included accessories, such as trading cards, will be included. Mini photobook: Chaewon Trading cards: Nako x2 There is a signature on the sleeve. I have stored it carefully in a dark place. Please purchase only if you understand that it is stored by a private individual. * There are minor scratches on the sleeve. I will package it with bubble wrap and waterproof protection for shipping.
