Fiberglass Prep Pen, Clean/Preps Metal Contacts
The Prep Pen is a tool that has thousands of uses around the workbench and home. The Prep Pen will ready a spot on a PC board to receive solder, clean rust off your side cutters, remove oxidation from a bulb socket, clean corrosion off a battery connection, remove grit from a card edge contact finger, prepare a surface for solder or paint plus thousands of more uses too numerous to mention.
The Prep Pen contains over 20,000 glass fibers that are thinner than human hair, but stronger than steel when it comes to cleaning and sanding strength. Further, the Prep Pen's body is designed for comfortable, secure grip. Each pen comes with two cartridges, one installed and one if the handles storage compartment. The fibers retract into the handle when not in use.
The Prep Pen goes where other tools and sand paper cannot reach. Use it like a pencil eraser, but it reacts like a sand blaster.
