Using this duvet cover set is easy. First, open the button closures at the bottom of the duvet cover. Then, place your comforter inside and use the corner ties to secure it so it won't move around. Put the shams on your pillows by opening the overlap closure at the back. For care, always machine wash it cold and separately on a gentle cycle. Tumble dry it on low. Don't bleach or iron it. A commercial washer and dryer are recommended as they provide more room for the duvet to move around during the wash. Since it's OEKO - TEX certified, you know it's free from harmful substances, so you can enjoy a healthy and comfortable sleep. Just remember, the insert is not included, so you'll need to use your own.
