Perfect rigid plastic cover on the back and flap with touch interactive window NILLKIN original mark (purchased from Ukbettershare). (Be careful to work with the opening magnetic closure system must be activated in "Settings" then "View" and activate all the way down "cover window"). Allows answering and call without opening the cover thanks to its speaker cutout. Automatically unlocks the phone automatically displays the opening and closing time in the small window. Perfect protection. Might be just earned a flap locking tab as NILLKIN does on her phone cover. Recommended.
