ABSTRACT:
A nib for use in a capillary feed marker. According to a preferred embodiment of the invention, the nib comprises a bundle of substantially parallel, absorbent fibers fashioned into a porous structure, some of the fibers being made of a water-soluble (or solvent-soluble) material, other of the fibers being made of a water-insoluble (or solvent-insoluble) material. By dissolving the soluble fibers of the nib while keeping the insoluble fibers of the nib intact, capillaries of an enlarged size may be formed in the nib.
