Abstract
A case assembly of a media binder includes a front surface board and a back surface board. Each surface board includes an inwardly facing surface and an outwardly facing surface and a cover sheet, and each cover sheet is wrapped around the outwardly facing surface of one of the surface boards. A marginal edge is attached to the inwardly facing surface of the surface board, and another marginal edge is unattached to the inwardly facing surface of the surface board. An end of the unattached marginal edge includes an extra edge extended from the unattached marginal edge, and the extra edge is folded against the unattached marginal edge. The unattached marginal edge is attached to the inwardly facing surface of an adjacent surface board to form a corner wrap around a corner of the adjacent surface board.
