ABSTRACT:
A two-way reusable envelope useful for commercial mass-mailings is disclosed. The envelope includes a window aligned along the bottom right-hand edge of the front envelope panel, thereby enabling standard Postal Service zip code bar code markings to be visible during both trips of the two-way envelope. The envelope additionally includes a two-portion closure flap which enables Facing Identification Marks and appropriate postage to be visible from the front of the envelope only during one trip as appropriate.
