Abstract
A holder for an auxiliary nib is disclosed which is intended to be fitted on the body of a main marker pen when a finer line is to be drawn. The auxiliary nib holder has as its outer end a cavity in which fits a length of ink-permeable material in ink-transfer contact or relationship with a projecting fine nib. Also seated with the cavity is an axially-movable preferably globular wick which is prevented from falling out of the inner end of the cavity, e.g. by means of an end rib. The globular wick is of controlled and known permeability, so that ink is able to flow at a known and acceptable rate to the fine nib when the auxiliary nib holder is in position in the marker pen and the globular wick is engaged by the marker nib.
