This is an unused item that has been stored at home for a long time. It can be used as a key case, coin case, or commuter pass holder. I'm not sure if the color of the button is originally this way or if it has changed over time. I don't think it's rust, but please check photos 7 and 8. I don't see any noticeable scratches, but there may be very fine ones. Please take a look at the photos and understand the condition before considering a purchase. Thank you.
