A writing instrument containing an ink reservoir, a writing medium, and a writing tip. Advantageously, a superabsorbent polymer can be associated with any writing instrument element or component, in order to absorb a writing medium to an extent sufficient to prevent abnormal or undesired leakage of the writing medium. The SAP can include, but is not limited to, polymers or copolymers preferably present at or near the surface of the writing instrument element or component in an amount such that the SAP does not substantially interfere with the desired communication or flow of the writing medium from the reservoir to the writing tip during normal use. Writing instruments according to the present invention should exhibit increased writing medium leak resistance.
