Thank you for viewing. (Management Number A) I am selling a men's long-sleeved shirt with a blue-based check pattern. I wore it only once, and have stored it in a dark place since then. The size is men's M, but it's a relaxed fit, like an oversized garment. Please be aware that this item has been stored in a regular household and that I have a cat. Immediate purchase is welcome. Please refrain from requests for price reductions or negotiations. Thank you.
