ULTRA HARD GLASS Screen Protector for Xperia 1 VI / 1 VII
The "ULTRA HARD GLASS" is Deff's first screen protector to use Dragontrail® Pro glass by AGC, a premium Japanese manufacturer.
It utilizes the original 0.4mm thick glass panel without any thinning treatment, preserving the material’s full strength and delivering ultra-high durability beyond its class.
Compared to Dragontrail® X, Dragontrail® Pro has a thicker stress layer, providing exceptional toughness and resistance to cracking.
Each glass surface is also treated with a special anti-smudge coating, making it resistant to dirt and easy to clean.
Smooth Large-Radius Curved Edges for Seamless Touch
ULTRA HARD GLASS is more than just thick and strong.
Its edges feature carefully crafted large-radius rounding, eliminating any unpleasant feel when swiping across the screen.
The soft, refined edge finish resembles that of a luxury watch crystal, enhancing the premium look and feel of your Xperia device.
Precisely sized to align right up to the edge of the display, the glass blends in as if it were part of the original design.
Stronger and More Crack-Resistant with Advanced Processing
Typically, screen protectors undergo a slimming process after receiving the raw glass panels from the factory—thinning them to the desired thickness before shaping.
However, for tempered glass, any damage during this process can significantly compromise its strength.
ULTRA HARD GLASS intentionally skips the slimming process, instead using the original 0.4mm thick glass panelas-is.
It then undergoes heat tempering and surface treatments while preserving the full structural integrity of Dragontrail® Pro.
This approach minimizes processing damage and allows the glass to maintain its superior strength and crack resistance.
