This is a UNIQLO AIRism jersey polo shirt. The collar has some discoloration. Color: Navy (almost black) Size: M Please understand that this item has been stored at home for a long time before purchasing. There is a faint stain on the right shoulder (see photo 6); I didn't notice it while wearing it. You can buy it immediately. No price reduction, no returns or exchanges. Please be aware of this. There are wrinkles because I haven't ironed it due to a large-scale decluttering.
