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

Great product

The header says it all.

The Steel and Brass bristles work as well or better than the fiberglass bristles for my purposes, and dont have the hazards of fiberglass. I win.

Works just like I needed them to

Well worth every penny paid.

Received these today. Ordered them to clean up an old flashlight that we love and cant replace. Started with the Brass Wire. Within the first 5 seconds it was coming apart. The wires where falling out and pushing back into the handle. At first I was able to get them to come back out. But after 3 minutes or so, they were back up in the handle and would not move. Next was the Nylon Bristle. It came apart in my hand while I was removing it from the package. I was able to get it to snap back together for a few minutes use before it came apart again. Needless to say, the two brushes I used are an EPIC FAIL! Not sure about the Steel Wire and Fiber Bristle. I did not use them. Writing them off as a learning experience. Do yourself a favor, keep looking.

Great set of brushes. Case is cheap and horrible but the brushes work great for scuffing parts and getting corrosion and solder mask off of pcb boards

These little brushes are retractable which is helpful to control the stiffness of the bristles, that said the bristles in the metal brushes are a little sparse, but work for what I want them for. I am satisfied with the price and quality.

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 use mine on my modeling/sculpting bench. They work great, and its wonderful to be able to retract and protect the bristles when not in use.
