This is a long-sleeved shirt in a 160A size for a school uniform. Although it is a school uniform, the specifications are the same as a general dress shirt, so it can be used for business, formal occasions, etc. I received a large quantity from an acquaintance, so I am selling the ones I don't need for myself or my family. Therefore, it is only available while supplies last, and there will be no restocks. It will be delivered in simple packaging. Thank you for your understanding.
