Firstly Shock Absorptive Cushioning Layer and Shock Dispersive Cushioning Layer make double cushions for any external shocks. Shock Absorptive Cushioning Layer would be the first barrier which absorbs the most of the shocks and the rest of it (if there is any) would be dispersed by Shock Dispersive Cushioning Layer.its unique technology has overcome one of the general weak points of most of shock absorptive have – high elasticity- thanks to the Stretch Resistant Layer.Air bubble–releasing / Repositionable Silicon Adhesive Layer is made only for users attaching convenience. The layer enables re-attaching and spontaneous dispersion of little air bubbles.FeaturesShock AbsorptionSpecial layers protect the device by absorbing the impacts from such accidental hits and/or droppings.Air Bubble-releasingThe Premium Silicon Adhesives make the small bubbles, which may appear during the attaching process, disperse within 24-48 hours.Stretch ResistanceHave you ever experienced a shock abortion lengthened and thus it has become no longer good for your device while you are attaching it? You are now free from the kinds of experience thanks to the Buff Lab's advanced stretch resistance technology.Non Slip GripBUFF may low the chances of losing your device form your hands by providing non-slippery skin texture.Quick & Easy InstallationAir bubble–releasing / Repositionable Silicon Adhesive Layer is made only for users attaching convenience.
