Abstract: An envelope for holding contents and receiving a date-indicating means having a plurality of panels connected together to form at least one pocket. The envelope has a closure flap moveable between an open position that allows the contents to be placed within the pocket and a closed position for sealing the contents within the pocket. A detachable receipt-defining portion is connected to one of the plurality of panels by at least one connection line. A field for receiving the date-indicating means is positioned along the connection line. After the date-indicating means is applied and the receipt-defining portion is detached, the closure flap seals a remaining part of the field when in the closed position.
