【The Secret to Maximum Correction!】 Some posture supporters only have a belt structure with no support, or are supported by easily breakable plastic bones, which leads to the problem of no actual corrective effect. To address these issues, we have specially appointed Mr. Hiroki Shimasaki, a Japanese physical therapist, as an advisor. Relying on human engineering principles, we have painstakingly developed a "metal bone" version of the back muscle supporter. When worn, you'll instantly feel a comfortable sensation as your back is pulled upright! It provides stable support even after long hours of wear, unconsciously maintaining your posture and preventing it from easily collapsing. This is the "core secret" of the excellent corrective power of the DEZIYUA Posture Belt! The metal bones are cleverly incorporated into the layers of the back muscle supporter, without poking or being noticeable, and feel light and comfortable when worn. 【Change Your Posture with Just One! ~For Beautiful Posture~】 The DEZIYUA Posture Supporter is your secret weapon for achieving correct posture! It corrects various posture problems such as rounded shoulders and hunched shoulders, while providing strong support to the back muscles. Whether at work, doing housework, exercising, studying, or going out, this posture belt fits snugly around your entire back, unconsciously supporting the habit of correct posture. By wearing it for just 2 hours a day, you can feel positive changes in your body in just 21 days and achieve beautiful posture. Become a truly posture-perfect beauty and regain your confidence! Note: You may feel a slight discomfort when wearing a posture supporter for the first time, but don't worry. Shorten the wearing time appropriately and gradually get used to it.
