New type of ball-point pen, characterized in that the appearance or concealment of the retractable tip or graphic ball by means of the pressure in a pulsator existing in the back part of the ball-point pen is such that if, starting from the resting position, with the tip or hidden ball , a first deep pressure is made on the button, which makes that point or graphic ball appear, and that first pressure ceases, such a ball or point will remain outside and fixed, ready to write; while when starting from that position a second pressure of the push-button is made, like the previous one, and in that second pressure it is stopped, the tip or graphic ball will be completely hidden, returning to the initial or resting position.
