ULTIMATE PROTECTION AND USABILITY: Our Premium Tempered Glass Screen Protectors are designed to protect your device screen against impact, scratches, dust and fingerprint smudges. Manufactured from a high quality chemically treated glass, the screen protectors are lightweight, thin but most importantly, extremely protective. A specially coated adhesive means the screen protector is perfectly fitted to your mobile device, ensuring that the clarity and sensitivity of your touch screen are not reduced. HARDNESS: Industry-high hardness: Effectively resists scratches up to 9H (harder than a knife). OLEOPHOBIC COATING: The Oleophobic coating built in to these screen protectors is a special oil-repellant coating which prevents oily fingermarks from sticking to the screen, so that they can be easily wiped off without leaving hard to remove dried on smudges. This protective oleophobic coating is invisible to the eye, giving these screens a high-transparency as clear as the phone's glass itself. EASY INSTALLATION: Due to their solid nature, tempered glass screen protectors are much easier to fit and less error prone than standard screen protectors. For the most hassle free, bubble free installation, please see and follow carefully the detailed and easy step-by-step instructions included within the pack, for the most perfect fit. WARRANTY INCLUDED: Any manufacturing defects are covered by a 2 year limited manufacturer warranty. For any damaged in transit products, please contact the seller directly for assistance.
