- Comprised of small non-linting, non-absorbent fibers - Solutions applied are held in suspension between fibers creating a non-dripping sphere which contains the material until it is applied - Exact placement of solutions as small as 1/8 of a drop can be accurately applied - Bends easily into any angle for the placement of material in areas of limited access - Disposable - savings up to 60% are possible by the reduction of excess required by ordinary bristle brushes
