The new Tetra Force Shock-Twist flexible protective sleeve is made from technologically advanced materials that can dampen and distribute the vibrations generated by impact with the surface and is ideal for anyone looking for maximum protection for their iPhone 7. The innovative IDS (Impact Dissipating System) technology developed by Cellularline allows the energy generated by the shock to be distributed along all edges and the waves and vibrations generated by the impact on the surface to be compensated, thus avoiding possible damage to the phone's internal components. The soft, elastic material together with the inner protective tape protects against impacts and falls. The Tetra Force Shock-Twist protective covers are available in various colours. They're perfect for adding a personal touch to your iPhone while ensuring an unprecedented level of protection.
