A clam-shell container system can include first and second container pieces that are hingedly connected. The first container piece can include a perimeter and a hangable tab, the hangable tab having an opening configured to receive a rod. The hinge connection can be perforated, such that it breaks upon actuation of the hangable tab to open the container system. The second container piece can include a cutout in proximity to the hinge connection and the hangable tab. Accordingly, the cutout can provide clearance for the rotation of the hangable tab beyond the hinge connection. Further, the second container piece can have a perimeter having a shape substantially similar to the perimeter of the first container piece. The perimeters can form a substantial seal in combination.
