Note: Accurate measurement is essential to get the right size for your class window. Before ordering, please measure the window. It is best to add 3 inches to the width of your window and 3 inches to the length before choosing your size to ensure a proper fit. Packaging Contents: Made of 85% high-quality blackout polyester fabric, sold by panel. These blackout curtains are available in more colors, suitable for more classrooms, French doors, patios, living rooms, kitchens and home offices. EASY TO USE - Unlike many blackout blinds and curtains, no tools, fixings, mounting brackets or drilling are required. Strong adhesive tabs keep the curtain in place. Simply detach the strap with adhesive tape at the top so that the blind falls on the window and press the bottom of the blind in place to completely block the view of the intruder. Blockout and privacy: these soft and durable door and window blinds are made with an innovative triple weaving technology, which guarantees a 100% blockout capability, but it is crucial that they completely obscure the classroom to effectively ensure everyone's safety. Our blinds are much safer options than paper blackout blinds or blackout blinds for windows. Care Instructions: Requires little maintenance. Machine wash cold, gentle cycle with mild detergent.
