Uniqlo men's button-down long-sleeve shirt. Size is men's M. I have disposed of the product tag that came with the purchase, so I don't know the official product name. Please do not purchase if you are concerned. I have several similar items, and this one hasn't been worn much, so I'm selling it. It was used regularly, so there is a feeling of use, but I think it can still be worn. It was folded and stored, so there are fold wrinkles. When shipping, I will pack it somewhat compressed. Please understand. Please purchase if you don't mind any scratches or wrinkles. Please do not purchase if you are concerned. ☆ Please purchase with the understanding that this is a used item, stored at home by a private seller, and inspected by a private seller. If you are concerned or are a perfectionist, please refrain from ordering.
