The cassette liner comprises a sheet-like element (2) having formed therein a pair of holes positionable at the hubs (15) of a magnetic tape cassette. The holes have perimetral portions adapted to engage folded edges (10) of openings (11) defined by each half-shell (12,13) of the cassette at the hubs (15). The perimetral portions are adapted to assume a curved form with concavity directed towards the hubs (15) of the magnetic tape cassette upon said liner mask being coupled with one of said half-shells (12,13). |
