Using this duvet cover set is a breeze. First, open the zipper on the duvet cover and insert your padded insert. Use the corner ties inside to secure the insert so it doesn't shift. You can then put the duvet on your bed and add the matching sham for a complete look. When it comes to cleaning, just toss the duvet cover and sham in the washing machine as they are machine washable. But be sure to follow the regular care instructions for your washing machine. Also, since it's OEKO - TEX certified, you don't have to worry about any harmful substances. Just enjoy the softness and style it brings to your bedroom.
