This special ScratchStopper protective film has a fat-resistant layer that makes fingerprints less visible and easier to remove. The film reduces the presence of oil and grease residues that your fingers may leave behind on the display screen. The film does not affect the usability of the iPod touch. The film is matte with a slightly rubberized surface, which gives the touch screen a better grip, making it easier to use. The ScratchStopper film is cut to the size of the display and covers it completely. Once applied the iPod touch is perfectly protected and will operate as usual.
