Abstract: The mailing device of the present invention consists of a rectangular card having front and back surfaces. Front and back surfaces are divided and foldable into three corresponding sections; the front surface having first, second, and third sections; and the back surface having fourth, fifth and sixth sections. The device includes a window allowing dimensional contents to be viewed and supporting structure to resist crushing. A pocket feature allows money, notes, gift cards, etc. to be inserted by the consumer and mailed within the device. The pocket is hidden from view and located between the first section and fourth section of the mailing device. The pocket is closed by bending an envelope flap attached to the first section of the device over the fourth section of the mailing device. The envelope flap is further comprised of a low-tack adhesive strip providing securing means to the fourth section of the device.
