This is a participation prize T-shirt from the Kawasaki Tamagawa Marathon, men's size M. It's a collaboration T-shirt with Frontale and Brave Thunders, featuring prints of both characters. It's new and unopened, but I saw people wearing it today, and it doesn't seem to have a back print. - Color: Black - Design: Kawasaki Frontale, Kawasaki Brave Thunders Thank you for looking.
