Thank you for viewing! This is a loose, fluffy posture support for slouching. A posture support born from the idea of "cross-strapping"! With its loose, fluffy material, it easily straightens your back! Feel refreshed and comfortable from the morning! The fluffy fabric gently fits any slouching curve! It feels like your back is being pushed♪ You can even use it while sleeping. Supports slouching loosely at work, in the living room, and in bed! The cross point at the center of the shoulder blades gives you the feeling of being pushed in the back. It stretches the chest muscles that are contracted by slouching and contracts the back muscles that are overstretched, supporting the slouching curve towards a correct and beautiful posture. It's soft against the skin and doesn't tighten too much. ■ Product Name / Loose, fluffy posture support ■ Suitable Size / Shoulder width (35cm - 45cm) ■ Washing Instructions / Wash in water or lukewarm water (use a net) ■ Material / Nylon, Polyester, Polyurethane It's new and unused, but it has been stored at home, so I would appreciate it if you would consider this.
