Unlike the bulky, awkward 30-rack (which functions more like a piece of luggage) or the flimsy six-pack (which demands immediate consumption), the 12 pack is built for storage. It creates a "wall" of cans that offers a sense of abundance without requiring a dedicated appliance. It is the preferred unit for the stockpiler. To see a 12 pack of LaCroix or Coors Light sitting unopened in the fridge is to feel a sense of security; it represents potential relaxation.
