【The Secret to Maximum Correction!】 Some posture supporters only have a belt-only structure that lacks support, or are supported by easily breakable plastic bones, which leads to the problem of not having any actual corrective effect. To address this series of issues, we specially invited Mr. Hiroki Shimasaki, a Japanese physical therapist, as an advisor, and developed a meticulously crafted "metal bone" version of the back muscle supporter, relying on the structure of human engineering. When worn, you'll instantly feel a comfortable sensation as your back is pulled! It provides stable support even after wearing it for a long time, unconsciously maintaining your posture at all times, and will not easily collapse. This is the "core secret" of DEZIYUA posture belt's excellent corrective power! The metal bones are cleverly incorporated into the layers of the back muscle supporter, without sticking out, and the discreet design makes it light and comfortable to wear without feeling burdened. 【Change Your Posture with Just One! ~For Beautiful Posture~】 The DEZIYUA posture supporter is your secret weapon for achieving the 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 over 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 moderately and gradually get used to it.
