Like written by other buyers, the flavor of thesis gums is little lasting. So, the green tea flavor itself is not as pleasant as I expected. The Best Thing About These gums is indeed the xylitol, Which, besides not harming your teeth, actually does something good for them! Another negative side of this offer is indeed peoplehave to buy 4 packages at once ...! If you do not like them like Actually I do not, you are left with trying to convert them to your friends;)
