Please note that this film was made from hardened real glass and that 1-2 mm space was deliberately left to the edge of the smartphone. The smartphone displays are slightly rounded and therefore the film cannot lie there, this distance was deliberately kept.     
included :
1x hard glass pane on adhesive dust strips
1x alcohol cloth packed
1x micro dust cloth-----------------------------------
Information: Use alcohol cloth to clean "before" applying.

Extract from Wikipedia: Tempered glass is a type of glass in which mechanical stresses are specifically created in the material through heat treatment and thereby the breaking strength against mechanical or thermal stress is increased.
The finished glass workpiece is heated in an oven and then quickly cooled. As a result of this quenching, the surface solidifies and the external dimensions of the component now only change comparatively little. However, the warmer core continues to contract even more, as the thermal expansion above the transformation point is significantly higher than below it. This creates a permanent stress field in the component: a ball is preloaded both radially and tangentially, a plate is under compressive stress on its surfaces, while a neutral fiber runs in the middle under tensile stress.
Thanks to this frozen pre-tensioning, the tempered glass can compensate for significantly higher tensile loads than untreated glass. Since the compressive strength of glass significantly exceeds the tensile strength, this represents an overall improvement. However, a workpiece treated in this way can then no longer be cut non-destructively as is possible with untreated glass, be ground or broken. In the event of glass breakage, the component disintegrates into small crumbs.
Tempered glass is used wherever there are increased mechanical or safety requirements on glass, for example:
Window panes on vehicles (car side windows (toughened safety glass), front windows are laminated safety glass)
Pressure-resistant windows
Glass furniture
All-glass doors
Diving masks
Touchscreens
