The tube has perforations that are made of cardboard and have a rectangular, square or round shape. The perforations are formed on the edges, and the tube has a seam which is obtained by a fold of a material for forming a pad at the ends which reinforce the maintenance of the tube in its round shape. The seam of the tubes is modified so as to create a mark.
