Using these 3D black dark shark curtains is a breeze. Just use the hook top to hang them up in your desired space. They're great for blocking sunlight and adding a decorative touch. When it's time to clean them, remember to separate them into dark and light color batches. Put them in the machine and wash on a gentle cycle with cold water, keeping the temperature below 30°C. Don't worry about small size errors (±3 cm), they won't affect how they fit. Each set has two panels, so if the total width is 118 inches and length is 106 inches, each panel is 59 inches wide by 106 inches long. And keep in mind that there may be a little color difference from what you see on your screen because of monitor variations.
