mint pack
A collection of 3 or more assorted mints and/or mint gums in a small, clear ziploc bag with no writing on it. Mainly used for standardized tests, such as AICE exams.
Friend 1: Yo, I heard that mints can help you concentrate during tests.
Friend 2: Yeah, but the test doesn't allow opaque containers or stuff with writing on it.

Friend 1: Damn, guess I can't bring my Altoids.
Friend 3: Not to worry, I've got some mint packs.
Friend 2: Thanks bro, you're a lifesaver.
