Three special-shaped "metal spines" provide feedback to the brain not only for the spine but also for the sensation of the shoulder blades! This offers a more effective solution for posture improvement, setting it apart from conventional "forceful correction." ※Biofeedback is a technique that allows you to control sensations that are normally difficult to feel by providing feedback to the brain through a special device. 【3D Three-Dimensional Hold Structure】 The ergonomic 3D structure naturally guides your body into the correct posture. Combined with breathable mesh and support pads (under the arms), it achieves more comfortable posture improvement! 【From the Developer】 "The posture looked better after being forcefully corrected, but the discomfort and physical problems increased..." Our product was born to solve such problems. Please experience an approach that focuses on genuine posture improvement! ≪Notes≫ ● All items are stored at home, so please refrain from purchasing if you are concerned about this. ● Unused items are generally not tested for operation.
