Thank you for viewing from among many products. I will introduce a posture correction belt. How to wear it: Simply put your arms through and secure it with the strong Velcro! Anyone can easily wear it. Point 1: Two plates are inserted in the back, maintaining an ideal angle based on ergonomics. (It felt more like supporting rather than firmly fixing.) Point 2: Soft fabric is sewn onto the shoulder area, making it less likely to hurt even when worn for long periods. (There's a point in wearing it for a long time, but those with bad posture inevitably feel discomfort. This helped alleviate the pain.) Point 3: Just secure it at the waist with strong Velcro! (It's made of mesh fabric, so it felt comfortable to wear. It's very easy.) Color: Black Material: Spandex & Nylon Size: M size *Please refer to the photos. My thoughts after trying it: As I mentioned above, I was also quite troubled by my bad posture. This product has soft fabric sewn in, so it's fluffy and comfortable to wear, and I could wear it for a long time. I think anyone who is seriously concerned or wants to prevent bad posture will surely like it. *This product is not a medical device. It is only a supporter, so please be aware of this.
