This item was purchased from Nihon Best in January 2025. After purchasing, I used it by placing the mat on the futon before going to sleep. (See photo 2) The pad was secured with the included belt and applied to my stomach while watching TV. There are no noticeable stains or scratches. I will offer it at half price to someone who can use it! 150,000 yen ▶︎ 125,000 yen (Price reduced!) 125,000 yen ▶︎ 85,000 yen (Price reduced!)
