<p>A letter card or reply paid letter form consists of a strip with a series of folds (2 to 6) across it, dividing it up into a series of panels (AR, B, C, D, G, J). The panel (AR) one end being a flap. The panel (B) next to it carries two small flaps (7, 8) which bend inwards. These three flaps have zig zag edges which are adhesive coated so that when folded, the envelope so formed can be sealed down. The complete blank forms the envelope for sending and return, also message portions for sending and return. Other documents can be enclosed. The flaps (7, 8) or other parts can have holes (11) for filing.</p> |
