rabbitgoo Window Privacy Film Stained Glass Rainbow 3D Prism Decorative Iridescent Window Sticker Static Cling Suncatcher UV Protection for Home Heat Control, Clear, 17.5 X 78.7 Inches

This brand, while it does have an odd name, worked great for me and was inexpensive. It goes on with just water and a squeegee and comes off as easily. It lasted in my apartment kitchen window with no trouble almost two years. There's also so many different patterns, and so many do like stained glass, especially when the sun hits!
