Instructions
Purchase a screen protector like the invisibleSHIELD or ClearTouch protectors. Products like the invisibleSHIELD reduce fingerprints and are washable and reusable. The ClearTouch Anti-Glare also repels dust and improves handwriting recognition while preventing scratches and other damage.
Purchase a silicon skin cover for the most snug protection of all exposed surfaces of your PSP Slim. A variety of skins are available in different colors and designs. Many include a screen protector as well. Skin covers protect the PSP Slim during game play from accidental damage while still providing access to the buttons and jacks.
Purchase a durable travel case that fits the PSP Slim. A variety of travel cases are available online and in stores, including the officially traveler's case from Sony for the PSP-2000 and PSP-3000 systems. Most hold at least 1-2 UMD games, although separate travel cases for games are also available. Although some generic PSP cases will fit the PSP Slim, it is generally best to choose a case that indicates compatibility with your model when purchasing.
