The manufacturer clearly hired a mathematician instead of a marketing executive. "How can we fit more mints in the same space? Simple! Just arrange them in a face-centered cubic lattice with 74.05% space efficiency!" Meanwhile, nature's been doing this with atoms for billions of years without bragging about it. The universe's oldest space-saving hack, now available in fresh mint flavor.
