They require no tape or paste, they are self adhesive, but come down easily without damaging the wall beneath and leaving no residue behind. They are tough and scratch and tear resistant.

With most companies out there, you can select a photo from their library (size of the libraries vary with larger companies offering a wider selection), but you can also order custom wall graphics using your personal photos. The process is relatively straight forward and usually consists of simply uploading your photo to their website and specifying how you want it cropped. Prices also vary with size, very large sizes often costing over $100, but generally speaking there is a vinyl wall graphic sized to fit every price range.
