Waist support that securely fastens with dual tightening belts. - Type: Waist support - (Waist size: 80-100cm) - Materials: Polyester, polyurethane, PVC - Features: Securely fastened with dual tightening belts - Usage: Inner processing to prevent slippage during wear - Target: Unisex I tried it once or twice, but it didn't quite fit me, so I'm selling it. The box is slightly torn due to home storage. The product itself has no issues. It's the type that focuses on firm support rather than being gentle on the skin. You can see from the photos of the Velcro areas that it's hardly been used. I will ship it without the box, so please understand. Thank you for looking.
