Bolkin Premium Tempered Glass Screen Protector for Samsung Galaxy Note 3 1. HD transparency: The screen protector is 0.33mm thick and it is made of chemically treated, transparent tempered glass. 2.

The hardness of the surface is 9H, three times stronger than regular PET film, which prevents the protector from being scratched or broke by hard objects such as knives and keys. 3. High Sensitivity: There is strong silicone adhesive coated on the back of the protector, which makes the protector contact the screen seamlessly and thus will not affect the sensitivity of the touch screen. 4. Rounded-edge design: The edges of the screen protector are rounded, which can prevent the edges from chipping. 5. Easy installation: The glass screen protector is easier to install than those made of PET materials, which can ensure bubble-free contact with the screen.
