Thank you for viewing. This is a DOCTOR AIR stretch mat with a stretching experience and a gently warming heater function. I bought it in January 2023, and its operation has been confirmed. There is a record of the purchase date, and although it has been used to some extent, I believe it is still usable. It seems to be currently sold on Amazon for around 22,000 yen, but I bought it for 17,350 yen on a TV shopping program. Thank you.
