The Vortex is named for the graceful swirling lines and patterns, like waves along the length of the barrel, that are so skillfully blended in the resin materials.ﾠLibelle has purposely matched the Vortex to an almost agenda-sized ball point that is ultimately practical for todayﾒs need to take messages on the go and have a pen that can go anywhere with you.ﾠ Color, style, value, and convenience are all in this one writing instrument. Ballpoints accept parker style ballpoint refills.
