A protective cap and mirror unit for a cosmetic pencil having a sharpened tip. The unit is molded of plastic to define a small rectangular frame whose rear face is integral with a tubular cap, the entry of which is at the lower end of the frame, a mirror being mounted on the front face of the frame. In the storage mode of the unit, the tip end of the cosmetic pencil is snugly telescoped in the cap. In an active mode, a user holding the pencil in one hand and grasping the unit with the other hand, withdraws the unit from the pencil and then defines with the cosmetic pencil her lips or eyes as she observes at close range her face in the mirror.
