Au-ve-co® 18335 Prep Pen With Glass Fiber, Bare Tool/Kit: Bare Tool

Now you can thoroughly clean rust, dirt or wax from any tight corner, crevice or hard-to reach spot with 20000 glass fibers in a pen point. The fibers are finer than human hair yet stronger than steel when it comes to cleaning power. Sand paper can be too rigid to directly contact and clean the con tours of inside edges. Thus conventional sanding only cleans the high spots. The prep pen's glass fibers can be extended out (by turning) to ensure even the smallest recesses get cleaned.
