AK Interactive Fiber Glass Bristle Pencil

The abrasive scratch brush with fiberglass 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 glass fibers. The shorter the fibers showing, the more abrasive the action. Ideal for derusting, deburring & cleaning photo-etch & injected plastics. With these pencils you will have the right brush for the right job.

CAUTION: Do not touch the tip.

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