I'm selling this item because it was a gift that I won't be using. It's a warm jacket with a boa lining on the inside♡ The sleeves are made of nylon, not boa. Please be aware that the sewing may be imperfect as this is an imported product. Please refrain from purchasing if you are concerned about this. I have never used it, but the boa part may be slightly dirty from being stored, or perhaps it was originally not pure white. Although it is unused, please understand that it is a pre-owned item.
