A set of diskette envelopes (28) uniquely leaved together with pliant covers (26)(16) bound by a device such as a popular plastic comb binding (36), and fastened by a device such as a hook and loop fastener (20) so that the holder secures a set of computer floppy diskettes. The cover configuration includes an elongated flapped member (16) which can be scored (22) for easy folding around the end of the holder; which, upon closure, secures the contents, and the curve of which, when open, keeps contained diskettes from falling from the various leaves (28). The materials and design are chosen to deliver the holders'utility; and allow it to be easily and economically manufactured.
