B'z LIVE- GYM 2011 -C'mon- Purchased on December 15th at Kyocera Dome. It's a size S T-shirt. I wore it several times at the LIVE, and then stored it at home. It has a certain amount of wear, but I think it can still be worn without any problems. Since it is a used item, please refrain from purchasing if you are sensitive to such things.
