Was included from a recent bulk film purchase and I don't use Polaroids... So my loss is your gain. I have no information about the storing condition of this film. Only thing I can say is that one pack is closed and the other is opened...opened box and the foil is opened so the film is exposed. I'm presume it's still usable. The expiration is 05-2015.
