M.int Flight Mode => Bottle empty?

Hi everyone.

I recently get a "combo" M.Int Flight Mode bottle of 70 ml plus Tiziana Terenzi Chiron. It was an used one and was supposed to be almost full.
I'm going to sell both of them but don't know if Flight Mode is full or empty.. 😅 I try to see bottle content but wasn't able.

Anyone knows how much a full bottle weights?
This is the bottle
