This is a duvet cover from NANGA. It is new, unused, and unopened. Retail price: 11,550 yen It's a double size (190cm x 210cm), and made of 100% cotton, so it feels good against the skin and can be used all year round. The calm design, typical of an outdoor brand, blends well with any interior. I am selling it unused because I currently have no plans to use it. Please refrain from purchasing if you are overly concerned, as this is a personal sale.
