Unused, but stored at home. The seal on the package bag is peeling off. Please consider if you don't mind. Returns and refunds are not accepted. Thank you for your understanding. Since the thickness is barely within the Yu-packet Post size, I will ship it directly in a flea market-specific vinyl bag. Please note that the packaging will be simple. Price is not negotiable due to fees and shipping costs. I am also selling a similar size M Airism Cotton Crew Neck T-shirt.
