Using your new 3D curtain is a breeze. Just install it in your desired window easily. You can use it to block out light, keep dust away, and add a decorative touch to your room. When it's time to clean, you can either machine - wash or hand - wash it. If you choose hand - washing, make sure the water temperature is below 90℉ to avoid getting your hands scalded. Remove the curtain panels gently to prevent any injuries. Remember, each set comes with two panels. If the set size is 118 inches wide by 106 inches long, each panel will be 59 inches wide by 106 inches long. Also, don't be surprised if there's a slight color difference between the curtain and what you see on your screen, as this can be due to monitor settings. With proper care, your curtain will last a long time and keep looking great.
