The pen is removably mounted in a tubular holder carried by a fulcrum formed by a swivel joint comprising a ball having a diametrical, pen holder receiving bore and a pair of rings secured together entrapping the ball in swivelling relation between them. The barrel wall has two, opposed longitudinal slots and fingerpieces extend from one of the rings through respective slots thereby mounting the the fulcrum for manual sliding adjustment along the barrel (and pen holder) to alter an amplitude of the orbital movement of the writing tip and the figures described.
