This is a Chiba Lotte Marines Lee Dae-eun T-shirt. It's made of a dry-fit material. I think Lee Dae-eun goods from his time with Lotte are valuable. The size is M, and the approximate measurements are 48cm wide and 60cm long. It's very clean with no particular damage, but there are wrinkles on the sleeve patch. Since it's an old item, I cannot guarantee any deterioration due to aging.
