A packaged block of envelopes comprises a series of envelopes, retaining plates disposed on either side of said series of envelopes, and a peripheral holding binder. In the vicinities of each of two of its corners, each of the envelopes has at least one thickness compensation wedge having a thickness substantially equal to the thickness of its closure flap, so that the envelopes are of total thickness that is identical at all four of their corners.
