This shelf unit is so impressive. I installed it in less than an hour. The installation directions were complete with a paper you place on the wall that has the eight markings for where you drill the eight holes. My only recommendation is to not use the foam adhesive on the back of the paper grid because it stuck to my paint on the wall. Use blue painters tape to tape the paper onto the wall. I have this shelf unit placed at a location in my spare room that will attract attention to it from the hallway outside the bedroom. I am so happy I ordered this beautiful showcase piece.
