Abstract: A retractable marking device is provided having a casing in which a coil is tightly wound from which the marking device may be extended for use thereof. A housing may further be provided such that the casing is placed within the housing and the housing is attached to a device on which the marking device is most commonly implemented. The marking device may be a pen, pencil or other writing instrument or may also be, for example, a blunt-ended instrument for use as a pointing-type device. The tightly wound coil maintains the marking device in a retracted position so that the marking device is readily available for use. In addition, the marking device is replaceable with a substitute marking device or replaceable following depletion of, for example, ink contained therein.
