Zagg Skins for Galaxy S3
Although Zagg is mostly known for making screen protectors they also sell a solution for protecting the rest of a smartphone. Rather than adding a case to the phone, Zagg skins protect the body of the Galaxy S3. Zagg skins are made of the same material as the Zagg InvisibleShield so they are scratch proof. The user can choose from designs that are already on Zagg or they can upload their own image. The skins also adds grip to the phone and are easily removed with little to no residue.
