The device has a pocket (3) which is open along the remote edge (15) of the sheets (1,2). The sheets can be inscribed on their exposed surfaces. The pocket has at least a first bending line (4,5) which extends parallel with and at a distance from two of the side edges (12,13,14,15). The device is normally to be arranged in the folded state of the first bending line. |
