Review on Premium Decorative Mosaic Heat Control Window Film For Home Office Bathroom Bedroom, 17.7 X 78.7 Inches by Lisa Gunterman

I was scratching my head for several minutes trying to figure out how this was going to stick because there is no indication of a protective film on the wrapper or on the directions. I had to read it in these reviews. So please save yourself the time. After that, it was so easy to put up. It's a narrow role so it didn't reach for edges of my window because I didn't want to take the time to install them horizontally. But upstairs windows it adds just enough privacy that I can use just window sheers as curtains. Let's me have a ton of light and privacy in the bathrooms. I'm very happy with this purchase.
