It doesnt seem like you posted over there. Oh well I dont know the exact length of time they will stay fresh but I read that if you put them into a freezer bag, squeeze the air out, then put the nozzle of one of those computer duster air cans into it and fill it up then put a bigger bag over it, do the same thing, then put it in a plastic bag and tie it. It should be pretty air tight. Then place them into the freezer. Voila.
