“GlassArmor is a thin plate of treated glass, protecting your phone’s screen against everyday scratches and bumps.
Due to several chemical treatments the glass has a hardness which can be scaled at 8~9H (H stands for hardness).
In comparison: a fingernail is no more than 2.5H, a copper coin about 3.5H and a general
kitchen knife’s blade is circa 5.5H.
The glass plate merges well with the actual screen, making sure it doe not affect its touchscreen function.”
