Looks like a marker pen but it’s really a compact portable tool set you’ll wonder how you ever did without! Lift the clipped cap to reveal two double- sided Philips/slotted screw bits. They fit neatly into the magnetic bit socket with handy LED light to illuminate the job. Or turn on the light when you need an auto light or flashlight. Horizontal level in the center lets you hang the perfect picture or wall hanging. All in a compact 5½” size. Includes one cell battery.
