Using these belts is easy. Just stretch them around your waist and they'll fit snugly thanks to the elastic material. When wearing, avoid pulling too hard to prevent damage to the rhinestones. To clean, use a soft, dry cloth to gently wipe the surface. Don't submerge the belts in water as it may affect the metal and elastic. Store them in a dry place away from direct sunlight to keep the color and shine of the gold and rhinestones. Also, be aware of the California Proposition 65 warning about the chemicals in the product.
