Fortunately, I was able to snatch a couple to try before my 16 year old son decided to do the disappearing item trick. It's a Magician like move that involves swiping the good stuff (money, mints, gum) from my purse and popping it into a pocket of his hoodie or the abyss known as his backpack.
I didn't even get a chance to tell him that they are sugar free! Alternatively, the mints are frosted with a combination of xylitol's cooling and flavor crystals. I thought they had a great taste much like other Ice Breaker mints and clearly my son agreed. I asked him for a few more and he informed me they were gone.
