On either side of the see-through screen is a piece of sticky plastic. You need to remove this before adding your poster. If you fail to do this the screen will look scratched, with dents and marks (in other words, pretty much useless.) I think some people have forgotten to do this, which is why the screen on the poster frame looks terrible. I put it together with the plastic on (first time) and it looked awful. Now, the screen is crystal clear and for the price it's a total bargain. The frames look like they cost much more when they're hanging on the wall. Black wooden frames with a nice finish. Don't let the negative reviews put you off.
