CoverBands were sleeves that go over MagicBands to give them styles. The first released packs of bands did not use the term “CoverBands” and came in a single size. The second generation of CoverBands included a cutout hole over the tappable portion of the band (the Mickey symbol) and cover in sizes small (S) and large (L).
