A container for storing and transporting letter mail and other flat articles, comprising a pair of side walls, a pair of end walls, a bottom member and a rim member extending outwardly from the side walls and end walls along the perimeter of the container, which are integrally formed as a unit. The side walls, end walls and bottom member define an enclosure for receiving articles. A removable cover member is provided for being positioned substantially in registration with the bottom member to cover the enclosure and protect the contents of the container. The container is preferably comprised of a lightweight material and manufactured using a thermoforming process. Rib members are disposed at pre-determined positions on the side walls, end walls, bottom member and cover member to provide structural integrity for the container. Adjacent ones of the rib members cooperate to form slots for receiving complementary rib members on another container so that the containers are nestable when empty with the respective cover members removed and stackable with the respective cover members positioned on top of the respective containers. The slots between adjacent rib members are adapted to receive dividers to separate letters according to their respective destinations.
