This is a genuine product purchased from an overseas Nike Golf shop. Although it's an L size, it's a bit large, so I've only worn it once. There are no stains or damage. I'd be happy if someone who can pull it off would use it. [High-Performance Material] This polo shirt uses Nike's DRI-FIT material, which quickly absorbs sweat and provides a comfortable fit. It's especially ideal for sports and golf. [Stylish Design] The black base with a dot pattern is a distinctive feature, making it suitable for a wide range of occasions, from casual to formal. [Brand Reliability] Nike is known as a leader in sportswear, and its quality and design are supported by many people. - Brand: Nike - Model Name: The Nike Polo - Material: DRI-FIT - Color: Black - Design: Dot pattern Thank you for looking.
