Using these belts is easy. Just buckle them around your waist and adjust the two buckles for a perfect fit. When using, be aware of the California Proposition 65 warning about the chemicals in the product. To maintain these belts, keep them away from sharp objects to prevent damage to the rhinestones. You can gently clean them with a soft cloth. Avoid exposing them to excessive moisture as it may affect the elastic and the finish of the rhinestones.
