When I was shopping at ZOZO, I wasn't sure about the sizing, so I bought both X and XL. X was the right size for me, so I'm offering the XL to someone who can use it. It's brand new and unused. This is a striped XL-size T-shirt commemorating SUPER BEAVER's 20th anniversary. - Brand: SUPER BEAVER - Size: XL - Design: Striped - Anniversary: 20th Anniversary Thank you for looking.
