A rotatable reel apparatus (10) for use in association with an axle (100) and the like, for operably winding, storing, transporting and unwinding various windable materials. A core member (12), having an inner peripheral surface (23) and an interior region (24), is operably sandwiched between a first (14) and second (16) corrugated paper platform member. The platform members (14,16) include a spindle region (18,18'), a plurality of core attachment flaps (31-34,36-39) and a plurality of spaced apart apertures (41-45). Each of the apertures (41-45) include distal edges (61-64) and proximal edges (56-59) wherein each of the proximal edges (56-59) are operably positioned adjacent the peripheral surface (23) of the core member (12), and each of the distal edges (61-64) collectively serve to define the outer periphery of the spindle region (18). The core attachment flaps (31-34,36-39) operably depend from each of the proximal edges (56-59) of the spaced apart apertures (41-45) and are folded inwardly toward, and into operable secured contact with, a corresponding portion of either the inner or outer peripheral surface of the core member. A concentrically positioned circular slot (50,50') is integrally formed within the spindle region of each of the platform members (14,16) to facilitate operable and aligned cooperation with, and rotation about the axle.
