Abstract: A clip for a writing instrument has an external biasing mechanism separate from the connection of the clip to the writing instrument to avoid permanent deformation or breaking of the clip arm and wear on the writing instrument body. The biasing mechanism is a coil spring mounted on the clip arm between two supports for compression and flexion when the clip arm is pulled away from the side of the writing instrument.

Abstract: A single writing instrument has multiple marking tips combined with a non-marking stylus tip. The single writing instrument is formed by two complimentary bodies which are joined together. The complimentary bodies are a front section and a rear section. The front section defines a chamber for holding ball point pen cartridges which are extendable one at a time through an opening in the front section writing tip disposed at one end of the front section. The opposite end or back of the front section is open and forms a sleeve for receiving the rear section. The rear section is bilaterally symmetric with a non-marking stylus at one end and one of a fountain pen tip, a rolling ball tip, a felt-tip marker tip, or a gel ink tip extending through a writing tip at the opposite end of the rear section. The rear section is adapted to fit into the open sleeve of the front section and be held by a frictional fit.
