Abstract: A container for holding a plurality of cassettes in a stored environment such as an album. Each container is comprised of a flat wall portion, side walls, and a single end wall together with a preformed top wall. The cassette is inserted between the top wall and the bottom wall from an end portion. The top wall has a center portion displaced from the bottom wall a given amount sufficient to allow the cassette to enter freely. The bottom wall is substantially flat whereas opposing end portions of the top wall are spaced a greater distance from the bottom wall in the center portion and a distance sufficient to clear the extended flanges on the cassette that are in close proximity to the head portion. The pair of spaced-apart end portions on the top wall allow the cassette to be inserted in either direction and without restriction.
