I need Help Trying To Find Licorice?

My grandmother loves licorice, but im not talking about like soft chewy rope licorice, or the hard rock licorice. The licorice she is trying to find is a super chewy licorice, like to where you have to chew your jaw out to eat it. My mother say that they use to sell it in the airports in an old country store around the country, but now we cant seem to find it. We thought it would be the best christmas present to get my grandmother, if any of you know where to find it, it would be greatly appriciated, Please and thank you
