CAT S40 - 3mk FlexibleGlass™ screen protector

Upgrade your CAT S40 with the 3mk FlexibleGlass™, a revolutionary hybrid screen protector that combines the clarity of glass with the durability of a film. Engineered to strengthen your screen by 250%, this break-proof solution ensures your device stays protected against impacts without the risk of dangerous glass shards.

Advanced Antimicrobial Protection

Stay protected beyond just physical damage. FlexibleGlass™ features a specialized silver nanoparticle-based coating that continuously eliminates 99% of bacteria, viruses, fungi, and moulds. This layer is safe for humans, does not wear off, and provides ongoing hygiene for your device.

Superior Durability and Scratch Resistance

Equipped with a ceramic coating, this protector offers 7H scratch resistance, shielding your display from keys, coins, and everyday abrasives. Its flexible, multi-layer structure ensures that even under heavy impact, the glass will not crack or chip, maintaining the integrity and clarity of your screen over time.

Precision Fit

Designed specifically for the CAT S40, this protector is laser-cut to ensure perfect alignment with all speakers, sensors, and cameras. It provides edge-to-edge coverage while remaining fully compatible with all 3mk Protection cases.
