Lancôme setting spray package symbol questions & discrepancy

[missxmas]

I just opened up a 1 ounce sized Lancôme setting spray called Fix it Forget it. While I have some ideas of what the symbols on the packaging mean, I would like to know what your thoughts are on what they mean exactly.. (If you know for certain, I would also like to know!). For example, what is the enlarged “e” that is in front of the 30ml ? What does the symbol with the swirly-like arrows mean? Or the triangle that contains the letter “PET” ? Lastly, I have a bit of a concern. The symbol that I believe indicates the suggested time period the item is appropriate to use for, on the bottle of this item Fix It Forget It Lancôme setting spray, says “6M”... while the box it was packaged in, says “12M”. This is the discrepancy I found that is actually very surprising to me that Lancôme would labeled these two differently.. is this a mistake? Is this on purpose? If so, why? It’s concerning because some consumers may look at the box & because it says “12M”, they may purchase it thinking they have a years use. When on the bottle it says “6M”. Maybe they will check the bottle or maybe they won’t, either way I’d like to know what what happened here.. If you happen to know anyone at Lancôme that addresses packaging, I am curious if my product was the only one labeled this way or if everyone has their bottle & box labeled differently.. if so, this does not appear to be consistent.
