A packaging container assembly having a variable length. The assembly includes an outer hollow body and an inner hollow body. The hollow bodies can be assembled with one another by a sliding of an open end of the inner hollow body into an open end of the outer hollow body for forming the packaging container assembly. Each hollow body has a rectangular cross section in a plane perpendicular to a longitudinal axis thereof thereby defining a plurality of longitudinal edges thereon. A plurality of rows of notches include a first set of rows of notches disposed on one of the hollow bodies, the rows of notches of the first set being disposed diagonally opposite one another on corresponding longitudinal edges of the one of the hollow bodies; and a second set of rows of notches disposed on another one of the hollow bodies, the rows of notches of the second set being disposed on all longitudinal edges of the other one of the hollow bodies. The first set and the second set of rows of notches are configured to latchingly engage one another for securely latching the hollow bodies to one another upon a pushing together of the hollow bodies, the first set and the second set of rows of notches fu…
