ABSTRACT:
This application relates to ball point type of writing and marking instruments and improvements therein whereby problems involving stick-slip phenomena and skipping, uneven writing and inability to write on greasy surfaces, as well as susceptibility to shock and distruption of continuity in writing are corrected by cooperating elements involving use of feeder rods, and utilization of flexed resilient filaments to modify friction relationships between the writing ball, its seat and a writing surface.
