A C-fold mailer comprises first (22), second (24) and third (26) panels foldable about a first foldline (28) with the first and second panels in registration one with the other and a second foldline (30) with the third panel overlying the back side of the first panel. Lines of cohesive (29, 40) are formed along the lateral margins and the first foldline of the first and second panels to adhere the panels one to the other, forming a return envelope. The first panel has a return flap (35) with rewettable adhesive. A third panel has segments of cohesive (46) adjacent its distal edge for registration and adherence to corresponding segments of adhesive.
