ABSTRACT:
An ink pen, particularly a roller type marker, includes a pen body provided with a fibrous body ink reservoir for holding ink, and a pen tip is provided on the pen body for drawing ink from the ink reservoir. The fibrous body ink reservoir is composed of a gathered bundle of unbonded continuous false twist stretch yarn fibers having twist and curl which are oriented generally parallel to one another and which entangle one another and are sufficiently randomly oriented with one another so as to form a strong tangled fibrous mass having high capillarity for good ink-holding properties while preventing leakage. The ink reservoir can be used with a film overwrap or extruded coating layer.
