Abstract
A perfected ballpoint pen, which alternately hides and pulls out its writing tip, by repeatedly pressing an axial button at the end opposite the tip, characterized in that the mechanism of the axial push-button is solved by sliding a prismatic prolongation of the push-button by a rectangular drill of a fixed piece inside the envelope of the ballpoint pen near the end, there being a spring that tends to push the button outwards.
