ABSTRACT:
An envelope formed from a single sheet of paper includes a front portion, a top flap, two lateral side flaps, a bottom flap, a top folding edge, two lateral side folding edges, and a bottom folding edge, the lateral side flaps overlapping and adhering to the bottom flap to form the back portion of the envelope. The top flap will adhere to the back portion after contents of interest are inserted into the envelope. The envelope further includes an opening device in the form of a piece of thin line disposed inside the envelope. The thin line loosely extends along one of the folding edges with its first end attached to one spot near one end of that folding edge and its opposite second end attached to an anchor portion on the outermost flap near the other end of that folding edge. The anchor portion does not adhere to any other flap.
