To use this duvet cover set, first open the button closure at the foot end of the duvet cover. Insert your padded insert and use the four internal corner ties to secure it so it won't shift around. You can then add the shams to your pillows for a complete look. If you want to enhance the coastal theme, consider adding the separately sold Euro shams and decorative pillows. When it comes to maintenance, this set requires dry cleaning only. Make sure to follow this care instruction to keep the duvet cover and shams in good condition. And since it's OEKO-TEX certified, you can rest assured that it's safe and healthy for you to use.
