Altoids "Curiously Strong Mints" have been a favorite candy of mine for many years. I don't indulge often, but when I do, the little red and white tin empties alarmingly quickly. I knock those bad boys down 2 or 3 at a time.
And those rectangular metal boxes with the snap-fit lid have a "Curiously Strong" fascination for some folks, to the point that numerous articles have sprung up around projects utilizing the empty containers.
Folks use them for everything from housing tiny computers to first-aid packs, and also for more mundane purposes like storing paper clips, or nuts and bolts (I keep my spare mini quadcopter propellers in an Altoids tin, for example).
