This is a long-sleeved T-shirt from CLUB TAMAPIYO. I haven't worn it much, but it's been stored since I bought it, so it's a used item. The size is "free," but the flat measurements are: Shoulder width: approx. 44 cm Body length: approx. 64 cm Sleeve length: approx. 58 cm I will ship it in simple packaging and by post, so thank you.
