Sentinel 4.1

Sentinel 4.1 Tempered Glass Protector For Back of LG Nexus 4

Doing things that a regular PET film screen protector cannot do, our Sentinel resists scratching and keeps your Nexus 4 Back free of fingerprints and smudges thanks to a special coating on the Sentinel. A special film is integrated in the Sentinel for a shatter-proof design that keeps both you and your devices glass back safe from cuts and scratches if the Sentinel becomes damaged. When a high-impact is suffered the Sentinel will crack staying in one piece and not shatter much like a cars windshield. A ultra-hard surface of 8H protects your devices rear glass from sharp objects and resists scratching from keys and other objects! Precision cut and crafted, the Sentinel 4.1 fits your Nexus 4 perfectly and has cutouts for the camera, flash, and speaker to allow full use of these features.

  • Special coating that resists oily residue
  • Beveled edge keeps you safe from cracked & chipped edges
