Abstract
A multi-color pen system is provided in which there are a plurality of liquid ink pen units, each of a different color. Each unit includes a nib and writing point, a collector element providing capillary passages for air and ink, and a tubular receiving body which houses the collector and forms an ink reservoir above the collector. Each unit is a complete, functioning pen device. The receiving body of each unit is threaded to receive a detachable pen holder to facilitate gripping the pen during use.
