<p>A reconfigurable envelope (1, 2, 3) has an open edge and a flap (3) foldable between a first position wherein the flap (3) lies within the envelope (1, 2, 3) and a second position wherein the flap (3) extends across the open edge to close the open edge, the flap (3) having thereon an address area which is concealed when the flap (3) is in the first position and is exposed when the flap (3) is in its second position, covering the address area on the front panel (1). A second flap (4) may be provided to seal the envelope when the first flap (3) is disposed within the envelope; this may be located on the front panel as shown or with the first flap (4) on the rear panel. Alternatively spots of adhesive (not shown) may be used to bond the top edge of the front panel (1) to the first flap (3). <IMAGE></p> |
