Thank you for viewing. This is Coolon, men's underwear. It's a short-sleeved V-neck T-shirt. I bought it for my son, but he said size L was sufficient, so I kept this one. It's unopened, but it's a vintage item. I can't see any yellowing from the outside of the plastic. I haven't opened it, so I can't see the contents. It's in a sealed bag. I apologize that I cannot guarantee the contents as it is unopened. Please purchase if you understand. #Men'sUnderwear #Underwear #Coolon #ShortSleeves #ShortSleeveVNeckTShirt
