Peel & Stick Wallpaper isn't a permanent solution but could last for several years depending on the conditions (it shouldn't be utilized in a humid area). It's great for rental apartments and dorm rooms where one can't "permanently" alter the walls, or projects like lining the back of a bookcase. It's more expensive to purchase but can typically be installed by a novice (non-professional). To apply, the back is peeled off to reveal the adhesive on the paper.
