Abstract: An insert construction for receiving an audio cassette single which is generally contained in a cardboard sleeve and sealed in a clear heat-shrink wrapped plastic cover and which is smaller than the usual plastic case which houses the multiple play audio cassette, enabling the cassette singles to be safely stored and displayed in the security packages heretofore used for the larger plastic cases. At least one generally U-shaped cross-sectional channel is formed in the insert and has a width generally equal to the thickness of an the wrapped audio cassette single for trapping and retaining the cassette within the insert.
