Abstract
An improved paper clip is provided which has three modes of use, one of which enables part of the paper clip to extend beyond the clipped papers for easy removal and visibility of the clip, another is partially hidden but partially extended for use as a bookmark, or the like, and the final embodiment is completely rotated against the papers so that it is essentially completely hidden.
