These 3D blackout curtains are super easy to use. Just hang them up using the free hooks in your living room or bedroom. They're great for blocking out light when you want to sleep in or watch a movie. To keep them in good shape, you can gently vacuum them to remove dust. For stains, spot - clean with a mild detergent. Remember, because of different monitor settings, the color you see on your screen might be a bit different from the real curtain. And each set comes with two panels, so make sure to measure your window space according to the size details provided.
