Using this bedding set is a breeze. Just put the duvet into the duvet cover, place the flat sheet on the mattress, and arrange the pillowcases on your pillows. For maintenance, it's recommended to machine - wash the set in cold water on a gentle cycle. Avoid using bleach as it can damage the polyester material. After washing, tumble dry on low heat. This will help keep your bedding set looking new and feeling soft for a long time.
