You are probably wondering why we have manga (comics) on some of our posts. Well, our screen protectors were specially designed to hold up to the most extreme sports enthusiasts and wherever they take their phones. Most of these comics talk about the new emerging sport of kiteboarding. One of the most extreme sports there is. We designed and engineered our screen to hold up to the most grueling situations. We engineered our special double tempering process to make a stronger and tighter bond than any other screen protector. We don't temper our glass once we temper our glass two times. This process increases the tensile strength of the glass. In laymen's terms it's pretty much the strongest glass you can get.
