Thank you for viewing. This is a short-sleeved sweater from GU (ジーユー). I think it can be worn on its own or layered with a long-sleeved inner. The size is men's M. I've worn it a few times, but as far as I can tell, there are no noticeable stains or dirt. I don't smoke, so there's no particular smell. Please refer to the photos for the condition, and only purchase if you agree to no returns and no claims. When purchasing, please understand that this item is stored at home. Also, when shipping, I will fold it to fit the specified size, so please understand this as well. Shipping will be done on weekends, so the number of days to ship is displayed as "ships in 4-7 days." Shipping may be changed between Yu-Yu Mercari and Raku-Raku Mercari depending on the packaging, so please understand. #UNIQLO #Uniqlo #Layering #LayeredLook #Indoor #Business #Casual #Commuting #School #ShortSleeve
