Transporting items of bulk, i.e., stacked documents or boxed merchandise, which vary in extent from time to time, in an envelope (22) that gives a desired favorable appearance of containing an item that is actually the content of the envelope (22), which motivates the recipient to open the envelope (22). The envelope (22) is rectangular and at least along three sides has isosceles shaped gussets (42, 44) characterized by progressively diminishing clearance between the sides in the direction of the apex (26, 40), so that the thickness or bulk of the item in the envelope (22) is effectively engaged by the sides (46, 48) of the isosceles triangles before significant shifting, particularly of stacked documents, can occur as might diminish the perceived bulk based on the external appearance of the envelope (22).
