Nature's Best Roaster, Large Black Base and Clear Lid

Nature's Best Roaster utilizes advanced engineering techniques, resulting in a 40% reduction in petroleum-based resins, while providing a structurally stronger container. Made of a unique blend of #5 polypropylene and natural, renewable resources. Lids are easily secured and will not crack like those made of polystyrene. Leak resistant lid fit eliminates the need to over wrap with film or tape. Double vents allow steam to escape more freely to reduce condensation buildup.
