Screen protector in durable film with optimal protection against scratches This screen protector is made of plastic with advanced technology that creates a product with enormous durability and scratch resistance. The film was first developed by the US Army to protect rotor blades on army helicopters during the Kuwait War. In fact, you can cut through it with your sharpest knife without it breaking. The protection is very scratch-resistant and resists scratches from, for example, keys and coins that you have in your pocket with the phone. The film has self-healing properties, which means that when it is scratched, the grooves are "swept together". The screen protector is treated with a substance that means that when you apply heat from your fingers, the scratches heal. Because the material in Copter Original Film is so incredibly tough, it is an excellent shatter protection for those times when a phone is exposed to such hard impacts that the entire glass screen shatters. The film holds all the glass shards of the screen together and protects you against cuts as long as the phone is usable. The screen protector is easy to install and when applied correctly, it does not create air bubbles on the screen. The thin material does not lose the screen feel. With the film installed, the display is just as sensitive to contact (click and swipe) as if it were not protected. Screen protector Original Film fits phones with both straight and rounded edges. It works very well with all mobile phone cases. It is transparent and fits perfectly at the edges.
