Flak 2.0 is real or fake?

I bought a Flak 2.0 from an official Oakley store here in Brazil, but I don't know if it's really original.

Points I noticed:

- Where the size is shown, there's no Oakley logo, but rather a square: "59 ◪ 12". The supplier told me that it's coming like that, is that true?

- The lens has different fittings, the fittings don't fit perfectly. Is that really the case or are they fake lenses?

- The name "Prizm" scratches when I run my fingernail over it, as if it were a laser. Is that true?

- The rubber on the temples seems to have a certain sticky material, the supplier told me that it's a waterproof material that they put on it, is that true?

- The frame box is very simple, see photo.

How can I identify the quality of the lens?
