Extendable pen, characterized in that it is constituted by several tubular elements telescopically coupled; each intermediate tubular element has one of its ends, the one oriented towards the writing cone, with the external beveled edge and an inner annular throat and at the opposite end it also has an external annular protuberance in correspondence with the inner throat; the internal tubular houses the ink reservoir inside it, the free end of which fixes the writing cone and at the opposite end it has an external annular protrusion, having in the vicinity of its free end a slightly conical peripheral circular projection towards said end and sharp cut in the opposite direction; the outer tubular has the end facing the writing cone configured in a manner similar to that of the intermediate elements and close to the opposite end another inner annular throat, covering said end with an appropriate element as a stopper.
