Our skins are vinyl decals that apply directly to the surface of your device. They are an appearance modification that can also protect the surface from scratching. The skins can last the device's lifetime or be removed at any time and replaced. Once you take the skin off, no residue is left behind. They also work with most 3rd party cases. If you are going to install a screen protector, we recommend installing that first before you install the skin. On devices with screens, install it on top of any screen protector. The skin can help hold the screen armor in place.
