These double satin flower elastic belts are super easy to use. You can wear them around your waist to add a decorative touch to your outfits. Just wrap them around your waist and adjust the tightness as you like. When it comes to maintenance, you can gently hand - wash them in cold water with a mild detergent. Then, let them air - dry. Remember, due to the California Proposition 65 warning, avoid direct contact with the skin for long periods if you're concerned about the chemicals. Also, keep them away from small children who might put them in their mouths.
