All parts of this accessory sets are really very useful: Protection bag: In contrast to the original Sony pocket this protective case is solid, that is, they can also do in a pocket without fear that it will have to be crushed. Screen protector: after I had delivered the PSP screen from dust, the film was placed on display. You "merged" directly to the display, and it was evident only at 2 places on the edge of the amounts of bubbles were slightly wegzumachen with SoftCard. Now the display is perfectly protected against scratches. UMD Bag: Very useful for getting the UMD Cases is in the long run annoying to lug around. Damper: Serves well as sunscreen UMD Cleaner: Good to remove lint and dust from the UMD Replacement analog stick: Useful if times the original Stick will be lost. Microfibre cloth: Good against dust and if the original cloth of the PSP has been lost.
