Kudos to Jo Mints for sending the free sample pack of Jo Mints and M60 mints, it arrived this week. Both are caffeinated with guarana. The standard Jo Mints come in the nicest box I've seen in a while, and there's a mirror in the lid. The box is a keeper. I can get the M60's locally, but not the Jo Citrus version, which I'd like to try.
