This is a professional collection cap from the Chiba Lotte Marines' 2021 Black Summer Weekend. The size is 60cm. It may be difficult to see in the image, but the "M" and "47" are embroidered with mint green thread. It has been worn to some extent, so I think there is some wear and tear. (I wash it by hand regularly.) Therefore, please refrain from purchasing if you are sensitive to this. Thank you.
