While most conventional screen protectors focus strictly on surface hardness, real-world drops and impacts often create microscopic cracks that quickly spread and shatter the glass.

To solve this, DeFF leverages NANOCERAM™, an advanced material that shifts the focus toward high toughness in addition to extreme hardness. Engineered with a uniform internal nano-crystalline structure, it actively contains and arrests cracks from spreading when subjected to daily wear and tear.

According to official data from OHARA Inc., NANOCERAM™ delivers a 20% increase in hardness and over 3 times the impact resistance in steel ball drop tests compared to high-strength chemically strengthened glass. By fully harnessing these exceptional material properties, this screen protector is precision-engineered to achieve the ultimate level of shatter resistance.

When dropping a smartphone, the impact on the display is instantaneous. NANOCERAM™ glass is structured to suppress the initiation and propagation of cracks, providing the high-toughness defense needed to protect the Xperia 1 VIII from daily accidental drops.

Custom-designed for the Xperia 1 VIII, every detail is shaped to respect the display area, sensors, and case compatibility without interference. The precision cutouts protect the screen without compromising the phone's sleek look or touch responsiveness, delivering an effortless, natural fit for daily use.

Includes an easy-to-use installation guide tool for a flawless application. Simply clean the screen, using the guide, align and place the protector, and press to secure—engineered for a bubble-free, perfect alignment every time.

The package also comes complete with an alcohol prep pad, a microfiber cleaning cloth, and a dust removal sticker, ensuring a seamless experience from screen preparation to the final touch.
