Abstract
Convenient disposable marker tip design minimizes marker passing distance and provides a constant width trace line independent of the angle at which the marker tip engages the writing surface. The marker tip comprises a nib shank, surrounding and supporting a nib having a partially spherical tip. The nib shank is shaped to provide maximum coverage of the nib surface and minimum passing distance between adjacent nib tips.
