Purchased from Nishimatsuya in January 2025. Size 50-60. There are no stains or dirt, but there are a few loose threads from the seams. I've trimmed them as much as possible. This has been home-laundered, inspected by an amateur, and stored at home, so please refrain from purchasing if you are sensitive to these factors. I will fold it compactly for delivery. Thank you.
