A multifunctional pen includes a penholder and a refill provided in the penholder. A clip is provided on the penholder. The penholder comprises an upper penholder and a lower penholder hinged to each other. The lower penholder may bend and tilt toward the upper penholder through a hinged joint. The clip is arranged on the upper penholder and across the upper penholder and the lower penholder. A tail end of the clip is raised and a pressing raised strips for a mobile phone is provided thereon.

A clip comprised of removably attached components. The clip may be attached to a writing instrument, such as a pencil, or stylus. The surface of the clip has male elements that allow the components to snap on to the clip so that the clip may be adorned. The components are secured to the clip so that they may rotate freely around the male element. The components may be comprised of decorative elements, such as jewels, initials, logos, or pictures. The components may be comprised of a utilitarian element, such as a lanyard, or a flashing light to indicate an incoming email. The components may have a tactile surface comprised of bumps, or waves. The components may comprise of movable elements such as a rolling ball, or star that spins. The tactile surface and moving elements of a component may aid in the treatment of anxiety and attention deficit disorders.

A clip attaching structure includes a clip supporting portion which protrudes on an outer circumferential surface of a main body, a clip, and a coil spring. The clip is configured to be rotatable with respect to a fulcrum at which the clip is engaged with the clip supporting portion. The convex portion is inserted into an inside of one end portion of the coil spring, and the other end portion of the coil spring abuts against the outer circumferential surface of the main body. A base portion of the convex portion has an outer diameter greater than an inner diameter of the coil spring, and a tip end portion of the convex portion has an outer diameter smaller than the inner diameter of the coil spring.

A multicolor writing instrument with an automatic return function includes a lower housing having a hollow cylindrical shape; an upper housing connected to an upper portion of the lower housing and formed with locking steps; a clip member hingedly provided on the upper housing so as to be movable about a hinge shaft; a coil spring resiliently installed between the clip member and the upper housing; pen cores filled with at least two different color inks; knobs having ends fitted into the respective pen cores; return springs resiliently installed between the pen cores and the knobs; and a return member formed integrally with the clip member on one side of the hinge shaft and toward the respective knobs.

A retractable writing instrument has a marking component for marking a writable surface. A barrel houses at a portion of the marking component, as well as an extension/retraction mechanism. The barrel has a slider portion. An internal magnet is adapted to operate the extension/retraction mechanism and positioned for operating movement along a length of the slider portion for extending and retracting a portion of the marking component. A slidable magnetic ring has an inner diameter for receiving the slider portion and is adapted to magnetically cooperate with the internal magnet.

An extension for pencils with wearing leads, formed from a thin-walled hollow profile. The inner cross section is adapted to the shape of a pencil. One or more slots of appropriate length in the longitudinal direction at an end of the extension where the tapered end of the pencil is located and a slight linear reduction in the cross section approximately over the length of one or more slots. Longitudinal raised sections in the form of triangular, square, and/or semi-circular prisms, directed inwardly. The height of the raised sections may increase in the direction of insertion of the pencil and dig into the pencil slightly when the pencil is inserted. The height of the raised sections is reduced linearly to zero at the end of the extension where the pencil is inserted. Inwardly bent or protruding retaining springs arranged on the inner surface of the extension.
