Pixiss Scratch Brush Pen Set With Replacement Tips, Fiberglass, Steel, Brass, Nylon, 5-inches Pen Style Prep Sanding Brush 4-Pack For Corrosion, Rust, Jewelry, Circuit Boards and Auto Body Work

Useful product and it arrived quickly

These work great when I’m building and repairing small electronic devices.

fast and graet service

This whole set costs as much as one brass bristle brush on Rio Grandes website. I can use them for different projects, with the primary being the brass brush for cleaning files.

They looked great. Concept is wonderful, but quality: epic fail! Each one them fell apart within moments of the first use. The actual handles are not glued together properly. Poor control of brushes...they just fall out. The best part about the purchase was the plastic pouch they came in. It was the only thing that did not end up in the rubbish!

Cheap construction, Labels on the pack and not on the pen - whats the use?!

Works just like I needed them to

I use these to repair circuit boards. Nothing else will do the jobs of removing foreign objects, old flux etc.

I ordered the whole set just to get my hands on the fiberglass scratch brush for electrical contacts. I had ONE that I used for at least 10 years but I had to leave it behind at work when I retired. This set of 4 various-fibered brushes looks O.K., but I eagerly got out the glass bristle one and twisted out a little stiff bit, and went at a tiny rust spot on a knife blade. Bloop! The fibers disappeared up into the body of the pen. Turned the advancing knob on the top. Nope. Nothing. Took the end off and there was the bundle of glass fiber. It wouldnt move except for a tiny bit and turning the knob did nothing. So, I guess thats what I have. Nothing. Just a broken pen and 3 more types for which I have no use.

The fiberglass one is the only one I have used so far. Perfect for cleaning enameling after getting fingerprints on it and before putting on another layer of glass enamel.
