I got to sample a pa(c)k of these thanks to CrowdTap, which is great because I always wanted to try them out. Obviously, there are no nuts or nut products in such a product. What IS there is a thin strip of germ-killing mintiness. At least in this flavor, the mint flavor is really really strong, but not unpleasantly so. I think that it is a peppermint flavor here. I'm interested in the other flavors for curiousity's sake, but this is probably my favorite, since it feels refreshing and not like a sweet treat, which is presumably bad for the teeth.
Anyway, the package is tiny tiny (maybe 2x1 inches) and that's awesomely convenient. The little strips pack plenty of refreshment, so it's the perfect size in my opinion. It also seems fairly long lasting - I ate ("ate"?) one about an hour ago, and I still feel a little vestige of freshness. Overall I think these are a great idea and adorable and functional, and they might replace my car mints if I can find them in-store! :o
