Thank you for viewing from among many options. I will introduce a posture correction belt. How to wear it: Simply put your arms through, pull, and fasten with the strong Velcro! Anyone can easily put it on. Point 1: Two plates are inserted in the back, maintaining an ideal angle based on ergonomics. (It's more of a supporting feel than a rigid fixation.) 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 to wearing it for a long time, but those with bad posture inevitably feel discomfort. This alleviates the pain.) Point 3: Just fasten the waist area with strong Velcro! (It's made of mesh fabric, so it feels comfortable. Very easy.) Color: Black Material: Spandex & Nylon Size: S size *Please refer to the photos. I understand how those with bad posture feel. I also do desk work most of the time, so I tend to slouch. Bad posture can worsen eyesight and lead to headaches, stiff shoulders, back pain, and neuralgia, which can become serious if left untreated. Then there's appearance. Honestly, people with bad posture tend to look less energetic. Wear the posture correction belt and be bright and energetic! I hope you can live a healthy life. My thoughts after trying it: I mentioned it a bit above, but I was actually quite troubled by my bad posture. This product has soft fabric sewn in, so it's fluffy and comfortable to wear for long periods. 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.
