The invention relates to a set of blanks for making a packaging box (1), to such a box and to a method for making such a box. The set includes a first blank comprising at least four main flaps connected together by first folding lines for forming the walls of the base (3) of the box, and a second blank including three panels connected together by third folding lines and including flips connected to the panels by a fourth folding line for forming the lid (2) of said box. A tearable flap (30) is connected to a flap by a perforated junction line (31), two flaps and two non-adjacent trapezoidal panels for forming the side walls and the base of the lid, wherein the two blanks are arranged so as to enable a sufficient covering in order to glue the same onto each other at the opposite inner and outer edges of the flaps and trapezoidal panels when the perforated folding line and the fourth folding lines are aligned or substantially aligned.
