A removable cap for receiving a writing implement includes a reverse clip. The cap has a hollow crown section for receiving the writing implement and an elongate cap extension that extends axially from the hollow crown section and includes an end that terminates in a clip flange. An elongate holding prong projecting substantially perpendicular from the clip flange and extending and opening toward the closed first end of the crown section in substantially parallel-spaced relation to the cap extension so as to define in conjunction with the cap extension and the hollow crown section, an elongate U-shaped slot, which is adapted to snugly engage an attachment material inserted into the slot. A gripping member is located within the U-shaped slot and is configured to intimately engage the attachment material inserted into the slot to assist in maintaining the engagement between the cap and attachment material when the writing implement is removed from the cap.
