This is an index long-sleeved knit sweater (•‿•) With tags. Size: L Color: Black Material: 50% Acrylic 50% Rayon Retail price: 2990 yen + tax I bought this a few years ago, but only tried it on and then stored it in the closet. Uses anti-static and moisture-absorbing heat-generating materials. It's thin, so I think it's easy to wear under a coat. Although it is unused, please note that there may be some pilling or rubbing due to being stored at home. Please refrain from purchasing if you are looking for perfection, as there may be other oversights. Please forgive any initial thread fraying or wrinkles that may have occurred during storage or shipping. The tag has wrinkles and folds. It will be folded compactly, compressed, and shipped in simple packaging. This is a home-stored item, so please only purchase if you don't mind and understand.
