This Easy Fix Zebra Roller Blind, also known as Day and Night Blinds, is made from 100% excellent polyester, offering good ventilation, anti-static, and dust-proof properties for durability. The blinds feature a combination of sheer and solid fabric in horizontal stripes, allowing you to manually adjust the density of indoor light and ensure privacy by isolating the external sight line. The safety design includes buckles and a chain connector that disconnects under a certain pulling force, providing extra protection for children. For interior mounting, the window depth must be at least 6.5cm, and the blind width should be 0.5cm narrower than the window. For exterior mounting, the blind width should be 6-10cm wider than the window frame to avoid gaps, and the length should be at least 15cm longer than the window length. The product size is 110x150cm in White. Please note that due to the top rail frame, the fabric width is 3.8cm narrower than the overall width.
