ABSTRACT:
An envelope for two-way mailing having opposed front and rear panels secured together around three sides to provide an open edged pocket, a first flap to seal the pocket is foldably carried on the edge of the pocket by one panel. A sealing flap is carried on the edge of the pocket by the other panel. The resealing flap is inwardly folded upon its panel and disposed within the pocket during the first mailing. A spot of adhesive at each end of the resealing flap between the said flap and its panel, adjacent the open edge portion of said panel, prevents the resealing flap from being severed from the envelope by the improper insertion of a letter opening device.
