Abstract
A roller ball pen for use with metallic inks, and a method for assembling the roller ball pen for use with metallic inks, is described herein. The pen body includes a housing that encloses a reservoir, a collet, a feed rod, and a tip. The feed rod transfers ink from the reservoir to a roller ball tip at a tapered end of the pen housing. In embodiments, the feed rod is embedded at a threshold distance inside the reservoir to provide an increased surface area for transfer of a metallic ink suspension. In further embodiments, a method of assembling the roller ball pen includes saturation of the reservoir with a metallic ink based on inserting a particular injection needle at a particular depth inside the reservoir.
