Abstract A two compartment interoffice envelope made from a unitary sheet of stock material folded to define a rectangular back panel, a rectangular intermediate panel hinged to one side of the back panel and folded against the back panel, a rectangular front panel having an opening therein hinged to the opposite side of the back panel and folded against the intermediate panel, a bottom flap hinged to the bottom edge of the back panel and folded against the front panel and a top flap hinged to the fourth edge of the back panel and cooperating with means carried by the front panel to secure contents placed within the envelope. Adhesive securing means are used to secure the front panel to the intermediate panel and to define a pocket adjacent to the opening in the front panel between the front panel and the intermediate panel. The bottom flap is adhesively secured to the front panel. Access to a pad carried in the pocket is available through the opening in the front panel. The top flap secures both material carried in the main body of the envelope between the back panel and the intermediate panel and in the pocket.
