Using these bags is super easy. Just open the drawstring and put in your items like jewelry, candies, or small souvenirs. Then pull the drawstring to close it up. When using them for events like weddings or birthdays, you can add a little tag with a nice message. As for maintenance, keep them in a dry place to avoid getting them wet. If they get a little dirty, you can gently wipe them with a soft, dry cloth. Don't put them in the washing machine as it might damage the satin finish. Also, be careful not to over - stuff the bags as they don't have a flat bottom and might lose their shape.
