I just scratched my invisibleshield easily! After applying it, I decided to do a tiny test with a plastic credit-card sized card that I had handy, and there's scratches... I'm certain that my iPhone wouldn't have being scratched!
InvisibleShield material is self healing. Give it a couple hours and the scratches will be gone.
Does that mean that the little dent that was put in mine while curing from a particle on my desk when I put it facedown will work itself out? (Didn't want to make a new topic when my answer is almost right here)
