To use these belts, simply wrap them around your waist or any part of your body you want to accessorize. You can adjust the belt easily due to its elastic nature. When it comes to maintenance, you can gently hand - wash it with mild detergent in cold water. Avoid using harsh chemicals or bleach. Hang it to dry in a shaded area. Keep in mind the California Proposition 65 warning. Don't let it come in contact with small children or pets to prevent accidental ingestion of the potentially harmful chemicals.
