Concept 5: Clamshell with detent snap and tear-off tab feature.

This clamshell has an aggressive snap-close feature facilitated by stylized snap buttons that mimic detents: One button has “spokes” that pierce outward from the button form; the mate is a replica of this, sans spokes. When the buttons are mated, the spokes act as a detent, arresting rotation or movement and therefore keeping the snaps mated tightly and the clamshell closed. The clamshell is opened by removing the “tear tab off” tab portion and opening the clamshell with the tabs at the bottom right-hand corner.
