BRUSH SET: This is a 3-piece pack of color-coded brush pens. Each tip is made of a different material - black is a steel wire tip, yellow has a brass, and red is a nylon bristle. A plastic storage pouch is included.
PEN STYLE: The brushes can be held just like writing instruments. They measure 4.5 inches (114mm) when the tip is retracted.
How to use: twist the end of the sanding brush pen to reach the desired length of bristles and stiffness as needed; It is recommended to turn it out to a length of about 5mm to make it more handy to use. The length of the tip will determine the firmness of the bristles – the shorter the bristles, the stiffer they will be.
MULTI-FUNCTIONAL: These brushes are ideal for removing corrosion on batteries, rust on cars, oxidation from watches and jewelry, as well as circuit boards and other electronics. Used to clean dirt, paint, scratches, and other build-ups.
