Simple belt for people with a hunched back or poor posture. The construction is simple but durable. It's easy to use because it's simple, and it's also convenient to carry. I think it would be great if you could use it like a backpack. You can adjust the shoulder area, so you can adjust it to your preferred size♪ I actually tried it, and I could feel that it was well supported, and my shoulders didn't hurt. Free size The shoulder strap length was 52 cm. I think it's a sufficient range to wrap around♪ Supporter Posture correction Posture improvement Hunchback correction Hunchback improvement Shoulder pain supporter Neck stiffness supporter 11
