Using these belts is super easy. Just wrap the belt around your waist and adjust it to your desired tightness. They're great for adding a touch of style to your outfit, whether it's a casual look or something more formal. When it comes to maintenance, keep them away from water as much as possible to prevent damage to the rhinestones and metal parts. Also, don't pull on the elastic too hard to avoid stretching it out. Remember the California Proposition 65 warning. If you have any concerns about the chemicals in the product, check out the website for more information.
