Tetra Force Strong Guard is the flexible, ultra-protective case with raised edges and reinforced corners made from technologically advanced materials that can absorb and dissipate the shocks generated by an impact. The IDS (Impact Dissipating System) technology developed by Cellularline uses the innovative Versaflex material, which distributes the energy from the impact and prevents potential damage to the external and internal components of the smartphone. It is combined with the antibacterial Microban technology, which prevents up to 99.9% of bacterial growth on the surface of the case and remains continuously active, as it is integrated into the material of the Tetra Force Strong Guard. The Tetra Force Strong Guard comes with a lifetime warranty.
