These belts are super easy to use. Just wrap them around your waist and adjust the elastic to fit comfortably. They're great for adding a bit of sparkle to your outfit, whether you're dressing up for a party or just want to look a little more stylish on a regular day. As for care, keep them away from sharp objects to avoid tearing the elastic or damaging the rhinestones. If they get dirty, you can gently wipe them with a soft, damp cloth. Remember, due to the chemicals in the product, don't let it come into long - term contact with your skin, especially if you have sensitive skin.
