Improved pencil, essentially characterized in that it is constituted by a body in the form of a cylindrical screw with an exagonal head, whose threaded end zone is delimited by another hexagonal head, and whose body is divided into two symmetrical portions, along the longitudinal axis of symmetry, and coupled to each other, by means of guide elements; each of its portions determines a cavity, ability to accommodate writer's objects and is conveniently closed by means of hinged covers; having provided as closure of the plumier, a hexagonal nut that threaded in the extreme thread, retaining the two constituent parts of the body of the screw.
