Abstract
This relates to a mailing envelope which may be utilized by one of the express mail services. The envelope is distinguished over existing envelopes by being provided with two closure flaps which permit the envelope to be utilized twice and possibly as a return envelope. In the first usage, the first closure flap is folded to an out of the way position beneath the second closure flap and becomes usable only after the second closure flap has been removed. The envelope also includes a removable label panel to which the second closure flap is initially bonded and is removed with the second closure flap when the envelope is first opened so as to permit the use of the second closure flap in the reclosing of the envelope and also to provide new surface to which mailing instructions, etc. may be applied.
