Authentic item imported from the SuperiorDefense official website. Product: Tank Of Strength Long Sleeve Tee Color: Black Size: US M size, equivalent to Japanese L size Purchased new and unopened, I tried it on once at home after opening it, and then stored it in a dark place. It's made larger than a Japanese M size, so even I, who usually wear L or XL size, could wear it. Please consider this as a reference only. This SUPDEF T-shirt is rarely available in the market, so this is a rare opportunity to purchase it at this price.
