To use this duvet cover set, first insert your duvet insert into the cover through the hidden button closure and secure it with the corner ties. You can enjoy the soft and cozy feel it brings to your bed right away. When it comes to maintenance, always machine wash it cold separately on a gentle cycle. Don't use bleach as it may damage the fabric. Tumble dry on low to keep it in good shape. And remember, never iron it. If your home washer or dryer is small, take it to a commercial one for a proper clean. This will help keep your duvet cover set looking and feeling great for a long time.
