ULTRA HARD GLASS Screen Protector for Xperia 1 VIII

ULTRA HARD GLASSfeatures premiumDragontrail® Pro glass by AGC, a leading Japanese manufacturer. It uses the original 0.4mm glass panel without any thinning process, preserving full material strength for superior durability. The glass features a thicker stress layer, delivering excellent toughness and crack resistance. Its surface is also treated with an anti-smudge coating, helping reduce fingerprints and making it 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 panel as-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.

“Nano Matte”

This type applies an ultra-thin, specialized matte coating to the glass surface, combining the clarity of the transparent type, the smooth glide of the matte finish, and effective anti-reflection (AR) performance. Striking the perfect balance between these three features.

Perfect Fit × Exceptional Touch with Multi-Layer Surface Coating

The screen protector features a multi-layer coating that delivers an ultra-smooth glide, enhancing your overall touch experience. It also offers excellent resistance to smudges — fingerprints, oils, and makeup can be wiped away effortlessly.

Additionally, in the event of accidental breakage, a built-in shatter-resistant film helps prevent glass fragments from scattering or causing injury, ensuring safer everyday use.

"Easy Alignment Tool"

Each product comes with a DIY alignment tool that makes applying the screen protector easy and precise — with zero frustration or misalignment.

HOW TO USE THE EASY ALIGNMENT TOOL

  2. Attach the alignment tool securely to your phone.
  3. Peel off the protective film from the adhesive side of the glass.
  4. Align and place the glass protector using the tool as a guide.
  5. If air bubbles remain, gently push them outward.
  6. Carefully remove the alignment tool (be careful not to lift the glass).
