"ULTRA HARD GLASS" has a strength approximately 8 times that of ordinary soda-lime glass and about 30% high
strength than the traditional Dragontrail series. It is one of the world's highest-strength chemically strengthened
glass, with the hardness exceeding 9H, reaching a Mohs hardness scale of 7 or above.
With the exquisite process technology, the edge of the glass protector is rounded to perfectly fit the phone screen,
presenting an all-in-one original appearance.
This product has obtained the "Made for Xperia" certification from Sony, ensuring its compatibility and reliability. As
the only certified accessory in the protective frame category, you can use it without concern.
1. Use the provided alcohol pad to wipe the surface of the phone screen, then use the eyeglass cloth to clean again
2. Attach the DIY tool to your phone
3. Peel off the protective film from the glass protector
4. Align the glass protector along the edges of the DIY tool
5. If there are any remaining air bubbles, gently push them outwards
6. Remove the easy application tool (make sure not to remove the glass protector)
After delivery from the glass original sheet factory, the protective glass undergoes thinning processing (reducing
thickness) and is shaped to the desired form. However, for tempered glass with delicate balance, any damage during
processing directly affects its strength. ULTRA HARD GLASS chooses not to undergo this thinning process and instead
maintains the original thickness of the plate (0.55 millimeters). It undergoes heat curing and gemstone processing to
minimize damage during processing and fully utilize the inherent strength of Dragontrail X.
