The perfect flexible protective case Tetra Force Shock-Twist is made of technologically advanced materials that can absorb and distribute the vibrations generated by impact on the surface, making it ideal for those seeking maximum protection for their smartphone. The innovative IDS technology (Impact Dissipating System) developed by Cellularline allows for the distribution of energy generated by shock along all edges and compensates for the waves and vibrations caused by impact, preventing possible damage to the internal components of the phone.
