A protective sleeve (1) comprises sheets (2, 3, 4, 5) of a flexible material. The sheets (2, 3, 4, 5) are arranged in four layers on top of each other, each sheet (2, 3, 4, 5) having a top edge, an opposing bottom edge and two mutually opposed side edges connecting the top edges and bottom edges. Each respective sheet (2, 3, 4, 5) is attached to an adjacent sheet along at least two opposing edges of the respective sheet so as to form a front pocket (7), a central pocket (8) and a back pocket (9). The central pocket (8) is open at the top edges and is adapted to contain a disc-shaped recording medium (10). The bottom of the central pocket (8), determining the depth into which the recording medium (10) may be inserted in the central pocket (8), is defined at a substantial distance (D) from the bottom edges of the sheets (2, 3, 4, 5). A holder comprises a flat bottom element carrying a plurality of ribs forming between them slots, in which are provided lateral projections for engagement with a fastening strip of the sleeves. |
