Abstract
Lapicero de mina recambiable, caracterizado esencialmente por un cuerpo completamente cilíndrico y alargado, por el cual pasan sendos lapiceros portadores cada uno de ellos de minas suficientes para su cometido, que al ser empujados unos a otros a medida que se vayan consumiendo se sacan del cuerpo general por un extremo mientras se va reponiendo por el otro extremo, consiguiendo una continuidad de escritura.
