The abrasive scratch brush with brass bristles is ideal for accurate and rapid cleaning, derusting and surface preparation on a variety of materials. The propelling pencil action exposes more or less of the brass fibers. The shorter the fibers showing, the more abrasive the action. Offers a robust abrasion, suitable for tougher cleaning and preparation tasks. Ideal for cleaning contacts, connection surfaces, plates, soldering points and for modeling to use in scenography to get textures on foam or scratches in plastic. With these pencils you will have the right brush for the right job.

Swivel mechanism for moving the brush: Twist the end of the pen to push or retract the tip.
