Supervised by an Anma Massage Shiatsu Therapist Deeply stretch the upper pectoral muscles, shoulder blades, and even the lower back while lying face down! Your shoulders will become more mobile, feeling light and comfortable ♪ I purchased this for just under 20,000 yen about two years ago on TV shopping. I've only used it 2 or 3 times, so I think it's in a clean condition. Operation confirmed, with instruction manual! I stopped using it because the position of my shoulders and pelvis didn't align well due to my short height. I think people of average height will be able to use it comfortably. There are no visible stains, and the operation is also fine, but please understand that this is a used item. There are no smokers or pets. Instant purchase is OK! Thank you for viewing. Thank you very much.
