Our solution lay with (naturally!) rare-earth magnets. With a 0.1" x 3/8" magnet held in a specifically designed thin-walled cup to provide attraction on both faces, you wear the cup on the outside of your shirt, which clings to a galvanized disc worn on the inside of your shirt. With the included half dozen broad-faced pencil clips slid onto an assortment of your pencils (or pens), you "wear" your pencil where it is always at the ready. It is held secure enough to not fall off from movement, yet is easy to remove or reattach without having to even glance away from your work.
Should you need more than six pencil clips, we sell additional ones by the dozen.
