This is a GUY ROVER shirt. It's made of thick 100% cotton with a vintage feel, and is a navy blue size L (it feels a bit small for GUY ROVER, so it's probably a Japanese L size). It's a shirt with a denim-like texture. It has been used (although I don't think there are any particularly large scratches or stains, I'm listing it as such), but it has a nice texture and I think it can still be worn for a long time. It was too small for me, so I rarely wore it. Thank you.
