I needed to replace plastic vertical blinds for a sliding door that were old , sloppy , and gross in my son’s rental condo. Did not want to spend the money for custom blinds. I took the chance and ordered. They are the best purchase I had made! They look fantastic, easy to install, and are by far, so much nicer than the plastic verticals that came with condo. The fabric is a nice weight, modern, and perfect for a guys place. They are room darkening, but you can see a very slight blurred shadow when the lights are on. I was hesitant with this purchase, but this was a great buy. Highly recommend!
