This SMONTER Easy Fix Zebra Roller Blind is made from 100% excellent polyester, offering good ventilation, anti-static, and dust-proof properties for durability. The day and night design features a combination of sheer and solid fabric in horizontal stripes, allowing you to manually adjust light density and ensure privacy by isolating external sight lines. For safety, it is equipped with buckles and a chain connector that disconnects under pulling force to prevent entanglement injuries. It supports both interior and exterior mounting with specific measurement requirements. The product size is 80x230cm in Grey. Note that the fabric width is approximately 3.8cm narrower than the overall blind width due to the top rail frame.
