Our day and night zebra blinds are made from 100% excellent polyester, offering good ventilation, anti-static, and dust-proof properties for durability. The design features a combination of sheer and solid fabric in horizontal stripes, allowing manual adjustment of light density and isolation of external sight lines for privacy. The safety design includes buckles and a chain connector to prevent injury to children. For interior mounting, the blind width should be at least 0.5cm narrower than the window width, and the window depth must be at least 6.5cm. For exterior mounting, the blind width should be 6-10cm wider than the window frame, and the blind length should be at least 15cm longer than the window length. The product size is 85x150cm and comes in a 2-pack of white. Please note that the fabric width is 3.8cm narrower than the overall blind width due to the top rail frame.
