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

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.

nice set for small jobs nice variety

They came apart before I used them the first time.

It is apparent when opening these that they are the lowest grade products of their type. In the first set I received, the Brass Bristle mechanism didnt push up. So I ordered a replacement. The replacement came today and now I see that the one labelled Steel Bristle is actually not steel. It is a second nylon or fiberglass bristle. I am debating whether to even bother ordering a replacement. Just be aware that they are of extremely low quality.

I got these to repair dings and dents on my cars paint jobs but I cant say they work. I watched a lot of videos on how to use them but either Im not a pro, or they just need a professional hand. Would not recommend at all unless you think you can figure it out.

Got the job done and delivered before promised

I would be happy to pay a little more to have a little better design. Out of the four brushes that I received, two of them failed when I tried to extend the bristles. The mechanism that pushes the bristles back and forth is a poor design. They work great when theyre in one piece. The pictures depict what happened when I tried to push the bristles out. The back end came undone.

Would be nice to include a pencil-eraser type of abrasive and a commutator dressing stone type.

Havent used them yet but build ok and looks like its work fine, also bought the replacement tips too.
