Nitori Hot Carpet 1.5 tatami mats Overall, it's relatively clean. I bought it and used it for about one season, but I haven't used it since and have been storing it. The sticker on the back peeled off when I wiped it. There's a little bit of pilling, like fuzz, on the corners. Thank you for your understanding. To prevent any trouble, we do not accept returns or refunds after purchase, so please be aware of this. Operation confirmed.
