Overview: This is merchandise from the instrumental band "CHON." I purchased it from their overseas official website and have stored it, using it very little. It's likely almost impossible to obtain now. Size: It's a free-size pullover with a versatile fit. Although it's labeled as M, it generally fits like a domestic L size. Functionality: It's made of thin, lightweight fabric with excellent heat retention. Ventilation holes are located under the arms for breathability and comfort. The pocket on the abdomen has a zipper, making it convenient for storing valuables. Comments: It's a remarkable item that combines practicality with intricate design, making it more than just band merchandise.
