A clip comprising at least one pair of parallel rails having a slidable member connected thereon is disclosed. The clip may be attached to, for example, a handheld instrument, such as a pen. The slidable member moves along the rails by a user's finger manipulation, stimulating the tactile senses of the user, and allowing the user to dispel nervous tension. Indicia, such as advertising, may be placed upon the slidable member. Also disclosed is a method of advertising and promotion in which the slidable member is used as a vehicle for advertising.
