She may be minimal wider (maybe 1-2 tenths of a millimeter) than the thickness of the original protective film,
which SONY ex works applied to the display, but that makes it easier to later changes,
especially when you do not want to damage when removing original film with the company logo of SONY.
For everyone else who contrary to the recommendation of Sony already removed the original film,
is the small plus in size no disadvantage (Fits exactly on the disc)
Liability is, a good surface preparation required (cleaning, degreasing), both on the original protective film, as well as directly on the glass equally well.

these here after not getting a few more days.
The peel-off from the carrier material is located on the long side of the film, what the just application much easier.
To avoid dust inclusions and blisters during application, it is quite helpful, one or two pots of hot or boiling water
directly provide added at the assembly site,
the steam binds fine dust particles and fluff in the air.
In some forums is even recommended the installation in the bathroom to perform and to fill the bathtub with hot water, but believe me
2 liters of hot water at the right place have the same effect as 250 liters in the wrong place)
