Abstract: A fastener assembly can include a latch of a first flap and a hole of a second flap. The latch and hole can be configured to be mated together to releasably fasten the first and second flaps to one another when the first and second flaps are in an overlapping configuration. The latch can be inwardly spaced apart from each outer peripheral edge of the first flap, and the hole can be inwardly spaced apart from each outer peripheral edge of the second flap. The fastener assembly can be a variable fastener assembly configured to be in a variety of predetermined fastened configurations for securing the first and second flaps to one another in a variety of predetermined overlapping configurations.
