Its happened to everyone - all you did was put your brand new phone in your pocket and somehow the next day the screen is scratched up. You did not drop it, throw it - or do anything but put it in your pocket but yet the display looks like your phone skidded down the highway at 55 MPH. Sad - but this story is 100% true and experienced by many people each day! Don"t let Coins, Keys, Money Clips or whatever else is in your purse or pocket destroy your expensive Samsung Galxy S4"s screen. Our Japanese PET Film is lab test and rated to be harder than fluorite and will protect your Galaxy"s screen against just about everything your pocket can throw its way except for a direct strike with a diamond (one of the toughest things known to man) - and hey if you keep loose diamonds in your pocket - then the cost of a new screen is probably not a concern for you. Our films are practically invisible to the naked eye once properly applied to the screen, and in no way cut down on the responsiveness or clarity of the screen. Installation is fast and easy - 3 Screen Protectors are included, as well as the cleaning cloths, in full retail packaging. Our Lifetime Replacement Warranty triple protects you - if anything happens to the screen protector in the life of the phone we will happily replace it free of charge - so you can know not only is your investment in your phone safe, but your investment in the protection is also safe!
