To use this duvet cover set, simply open the button closures on the duvet cover and insert your comforter. Use the corner ties inside to keep the comforter from shifting. The matching shams and decorative pillows can be placed on your bed for a complete look. When it comes to care, machine wash the duvet cover and shams in cold water separately on a gentle cycle. Don't use bleach. Tumble dry on low heat and avoid ironing. If your washer or dryer has limited capacity, use a large - capacity commercial one. For the pillows, spot clean them when needed. Remember, since this set is OEKO - TEX certified, it's free from harmful substances, so you can enjoy a fresh and safe sleep environment.
