Using these 3D curtains is a piece of cake. Just install them in your desired location and enjoy the beautiful view. When it comes to cleaning, you have two options: machine wash or hand wash. If you choose to hand wash, remember to use water below 90℉ to protect your hands. Each set comes with two panels, so make sure to handle them carefully when taking them off for cleaning to avoid any injuries. Also, keep in mind that the color on your screen might be a bit different from the actual curtains because of monitor settings. With proper care, these curtains will serve you well for a long time, maintaining their non - pilling, non - fading, and non - off - lining features.
