This product wraps around the waist for stability and reduces lower back discomfort. The cross-net sewn into the fabric provides broad support for the lower back. It supports the lumbar spine to the pelvis, restricting excessive movement. The breathable, thin fabric is designed to be less stuffy and comfortable to wear. Size: Large / L size (80cm～100cm) The box has some damage, but the product itself is unopened and in good condition. Due to shipping costs, the box will be disassembled and shipped with the product. Thank you for your understanding.
