This item is being sold for 8,000 yen by teenager shibuya. Other sellers are offering it at a bargain price, but I suspect the authenticity of those items as they lack images of the tag's reverse side. This item is authentic. This is a plain long-sleeved T-shirt that American Apparel produced for Supreme. After American Apparel went bankrupt in 2017, these T-shirts were left in their warehouse. They were abundant in the market until a few years ago, but their availability has been decreasing recently. The size is XL, and the color is black, making it a versatile piece. The fabric is thick. The SUPREME watermark is visible on the back of the tag, which proves its authenticity. Please rest assured that this is not a fake. 100% cotton MADE IN USA XL size Deadstock item Due to long-term storage in the warehouse, there may be some fold wrinkles. Please refrain from purchasing if you are sensitive to this or if you are seeking a perfect item. Please allow for some error as measurements are taken by a non-professional. Some shrinkage may occur after washing. Further shrinkage may occur if put in a dryer. It will be folded small and shipped in simple packaging.
