Instructions
Place stickers or decals on the device. Adhesive stickers can easily be applied to any controller, and can just as easily be removed. Topics of stickers can range from everything from unique designs to sports teams logos.
Place a snap-on outer case to the controller. These cases snap over the exterior of the current case and often have grips built into the back for increased stability.
Purchase a skin for the d-pad or other buttons on your controller. Skins are often created for individual buttons and, similar to the snap-on cases, fit neatly without ever having to take the controller apart.
