They can be applied from inside the window or outside.
They also can be full digitally printed on UV stable ink.
The most common frosty films are dusted frosting which has a little sparkle or crystal in it that reflects and regular frosting film.
The difference is that one when up close where as the other is more of a matte frosted glass look.
