Abstract: The present invention relates to a holder device that is mountable on a support and adapted to removeably secure elongated writing implements thereto. The holder device includes a base portion adapted to mount on the support and a pair of wing portions extending away from the base portion and converging toward on another to terminate in a free wing edge so that the wing portions and the base portion define a longitudinally extending channel sized to receive an elongated writing implement. The channel has a longitudinal mouth located between the wing edges whereby the writing implement may be inserted through the mouth into the channel. In the preferred embodiment of the present invention the channel has grooves therein to permit a variety of sizes of writing implements to be mounted. The invention includes alternative mounting structure, one embodiment has an adhesive layer on the base portion; another embodiment includes a clip structure for removeably mounting the device.
