Ablave One Way Window Film Non-Adhesive, Daytime Privacy Reflective Mirror Window Tint for Home, Heat Control UV Blocking, Static Cling Window Stickers Black-Silver, 17.7 Inch x 78.7 Inch. Very easy to istall. I started by removing my window payne, as if to clean them. Then it was easy to lay the film on it and cut it to size. I did this because I have a window bird feeder that I put on the outside of the window. Everytime I walked into the room, it scared away thwe birds on the feeder. Now they cant tell that I am there, And I can enjoy watching them more. #Viralix #Ablave #Hedyfu
