Using these stretch belts is easy. Just wrap them around your waist, hips, or any other part you want to accessorize and adjust the elastic to fit comfortably. When it comes to maintenance, keep them away from sharp objects to avoid tearing the straw material. If they get dirty, you can gently wipe them with a soft, dry cloth. Always remember the California Proposition 65 warning. Since this product contains chemicals like cadmium, lead, and nickel, don't let it come into direct contact with your skin for long periods.
