Abstract: A kit for assembly into at least a first reel includes a core and two flanges. The core has a substantially rectangular main body having opposing first and second axially extending edges and opposing first and second end edges extending between the first and second axially extending edges. The core also includes a first set of interlocking teeth on the first axially extending edge, and a first set of first connecting tabs on the first end edge. The main body is configured to be deformed or rolled into a cylinder in which the first set of interlocking teeth engage connecting features of the second axially extending edge. The first flange has an annulus and at least one axially extending rib or rim. The annulus includes receptacles for receiving and operably coupling to the first set of connecting tabs. The second flange is configured to couple to the core.
