"A PROPELLING PENCIL, ESPECIALLY FOR BLACK OR COLOURED LARGE DIAMETER LEADS" The present model refers to a propelling pencil, especially for black or coloured large diameter leads, the so-called non-polymerized leads, comprising a substantially cylindrical elongated body (1), a lead container tube (2) built in said body, having an end associated to a lead-fixing mechanism (3) that can be actuated by an actuating element such as a press-button (5) arranged at the other end, which is characterized in that the shape of the cross-section of the internal channel of the lead container tube (2) is other than circular, being especially poligonal, whereby the reception and storing of more than one large diameter lead is made possible.
