contained and implementation

it lacks a little alcoholic cleaner to thoroughly clean the glass.
very easy to install one is careful not to put the finger on the side that sticks to the screen, but once installed, it integrates itself
a small blue paper on the inside but no explanation has to know what it is and what to do with.
I did not find the tutorial on the ibroz site.
the home button is a bit more difficult to place

the level of protection as I received yesterday, I can not say anything yet about the quality of the product.
