Two-color ballpoint pen by inertia and percussion, the pen presents the following peculiarities: after a wrist shake a weight or hammer (6), which slides on some inner guides of the body (3) by the action of inertia ascend to reach the bouncer (1) descending then with more energy, (6) hits to (7), in the area (7c) and due to the inclination of the faces of both pieces, there is a descent and turn, due to the action of the spring (8) (this is retained by the screw (9)), the piece (7) will rise while a turn occurs, this rotation is due in addition to the action of the spring to the inclination of the tips of the guides and the faces of (7c), as (12) is joined to (7) by the area (7a) the turn is also transmitted to (12), this has connected the down mechanism formed by: (10 and 11), due to the action of the launching ramp that presents an inclined plane (and that has a step that quickly deactivates one of the mechanics downstream to avoid any problem), the descent of the element (10) is activated, that is, the corresponding color, the sequence in the launching ramp is p1-p2-p3, in the pieces (10) the cartridges are connected ink (5 and 5 ''), the piece (12) is restricted vertically partly between the pieces (3 and 4), but allowing the rotation thereof, the clip (2) is optional.
