Polo shirts, M, navy, unused, in bulk, Cool Biz I've gained some weight and can no longer wear them (changed from M to L), so I'm selling three shirts together. They are unused. There's one more shirt in addition to the three. This one has been opened. Please see the last photo. In other words, this is a sale of three unopened shirts and one opened (worn and washed once) shirt. I am not considering discounts. Cool Biz, summer clothes, business, travel, change of clothes
