An article of manufacture includes a first pad of sheets with a plurality of layers where the first pad of sheets perimeter is defined by a first edge, a second edge, a third edge and a fourth edge. The article of manufacture further includes a second pad of sheets with a plurality of layers where the second pad of sheets perimeter is defined by a fifth edge, a sixth edge, a seventh edge and an eighth edge. The first and second pad of sheets are releasably bonded together at the first edge of the first pad of sheets and at the fifth edge of the second pad of sheets by a first adhesive. The first adhesive forms a hinge structure allowing the first pad of sheets and second pad of sheets to rotate about an axis. The second pad of sheets are releasably bonded together at a portion of the bottom side of each layer of the second pad of sheets located at the fifth edge by a second adhesive. The remaining portion of the bottom side of each layer of the second pad of sheets is free of the second adhesive. Finally, the second adhesive has a peel strength less than the first adhesive.
