These are Uniqlo C's very popular sweatpants. I am a non-smoker and do not have any pets. I purchased these at a store and wore them about 3-4 times. There are no noticeable scratches or stains. The original price was 3990 yen on the online store, and with 500 yen shipping for home delivery, it would cost 4490 yen, but I'm selling them for 3500 yen, including shipping, with anonymous delivery.
