Built in technologically advanced materials that dampen and dissipate vibrations caused by impact with the surface, Tetra Force Shock-Twist is the new, ultra-protective and flexible case: the ideal solution for those seeking maximum protection for their smartphone. Thanks to the cutting-edge IDS (Impact Dissipating System)TM technology developed by Cellularline, the energy created by shocks along all the edges is dissipated, and the waves and vibrations caused by impact with the surface are counterbalanced, avoiding possible damage to the phone's internal components. The soft and elastic material, combined with the ultra-protective internal protection band, keeps your phone safe from knocks and falls. Tetra Force Shock-Twist cases are available in different colour hues, the ideal way to personalize your smartphone while providing an unprecedented level of protection.
