Fiberglass Scratch Brushes - pkg/4

Fiberglass Scratch Brushes The 4-piece set comes with color-coded pens, each with a different brush tip. The black pen is a stainless-steel tip, and the yellow is a brass metal wire head. The blue has a fiberglass bristle, and the nylon tips are in the red pen. The brush set comes in a plastic storage sleeve with individual compartments for each pen. The tips are retractable and operate by twisting the tip. If you keep the tip shorter, the bristles will be stiffer. Retract the bristles when the pen is not in use. This brush set is multi-functional and can be used for a variety of crafts.
