Thank you for viewing. This is a size M T-shirt. I bought it to use when exercising, but I haven't had many opportunities to wear it, so I'm selling it. There is a small stain on the upper back, so please refrain from purchasing if you are concerned. [Shipping Method] I plan to use regular mail. There may be creases, so please refrain from purchasing if you are concerned. Please note that we cannot guarantee delivery in case of loss or damage. Thank you very much. (^^)
