Poster Hangers are two strips of black plastic the slide on to the top and bottom of your poster. You then attach a small black hook to the top strip so that your poster can be hung from a picture hook rather than stuck to the wall. The bottom strip helps keep the poster weighted down. 

Poster Hangers come in three sizes, 62cm for vertical images and 92cm for horizontal images, and 102cm for larger posters you may own like horizontal movie one-sheets.

The hangers can be tricky to slide on and require gentle persuasion, patience and a sometimes two sets of hands. View an instructional video here: http://youtu.be/5yE1r6e5Itc
