Improved pen that essentially is characterized by being constituted from a piece, in extension of the envelope of the pen itself, which on the one hand serves as a centering guide for the ink container tube, while it has a threaded through hole, which receives the shank of a screw that has a concave bottom housing at the base of its free end, in which the spherical end of a spigot covered with virgin rubber is installed, which has the shape of a stopper, apt to be inserted, when turning the faceted inner housing cap in which the head of the screw engages, in the ink tube, thus sealing the side hole as atmospheric, which it incorporates.
