The remailable envelope consists of a front panel which may be provided with one or more optional viewing windows and which is integrally connected to a sealable top flap, a pair of opposed side flaps and a back panel; and a resealing flap integrally attached to the back panel. For first mailing, the resealing flap, containing at least two fold lines, is folded within the envelope pocket and mail enclosures are inserted therein.
