Abstract: An implement holder. The implement holder is detachably affixable to a pre-selected substrate such as a glass window, mirror, or other suitable surface, for removably securing a pre-selected elongated implement such as a pen or pencil in a desired location. The devices are adjustable in multiple axes, so that in spite of various angular situations encountered with respect to one or more pre-selected substrates, the implement holder can be easily adjusted to secure a selected implement, such as a pen or pencil, in a desired orientation. The implement holder uses as a detachable securement device a flexible elastomeric suction cup. The suction cup has an attachment portion that is detachably affixable to the pre-selected substrate. Connected to and opposite the attachment portion a support portion. A fastener is affixed to the support portion to adjustably and slidably secure an implement cradle to the support portion.
