Using this curtain is a breeze. Just install it in your desired location and enjoy the beautiful 3D map view it brings to your room. When it's time to clean, you have two options: machine wash or hand wash. If you choose hand wash, remember to use water below 90℉ to protect your hands. When removing the curtain for washing, do it gently to avoid any injuries. Since it's made of high - quality polyester, it can last a long time. But to keep it in top shape, don't use harsh chemicals during cleaning. And keep in mind that each set comes with two panels, so you get a complete look for your window.
