A multi-part mailing assembly includes a single-layer form of detachable parts related to each other. The assembly is combined with an envelope that both exposes and secures the parts and other contents for specialized mail handling. Spaced horizontal and vertical tear lines separate the form into multiple related parts. In addition, opposite marginal edges are also perforated for continuous pin or sprocket feeding of the stock through printing equipment. Additional vertical tear lines remove the margins after printing, and transverse tear lines separate the forms from each other. The envelope secures the parts after being detached from each other into position within compartments of the envelope along with other inserted materials. Open or transparent areas allow printed information on the appropriate portion of the related part to be seen from the outside of the envelope after it is sealed for mailing. One or more of the printed parts may be removed from its place inside the sealed envelope without disturbing or exposing the balance of the inserted contents.
