So here I bought this pack and shell protective film ... Well, nickel protective films, they are great and perform their proper roles. As for the "shell" ... this is very bad, I placed the shell on gsm and what ??? bin and the shell is cracked ... a few days later, I accidentally dropped my mobile phone, the hull must play its role, yes it does by protecting my mobile phone but fractures everywhere !!! For me, it is therefore a bad buy ... But I recall that the films are good
