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

They couldn’t scratch an itch let alone any metals. Don’t waste your money.

Useful product and it arrived quickly

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.

Fiberglass scratch pen was way softer than I was expecting, and the wire brushed splayed out really quick.

These are being used as one treatment when removing encrustations from ancient coins. They are used with little pressure in a circular motion and work very well.

This is great for cleaning electrical contacts and small connectors found in home theater/audio systems.

Seems like every battery operated device I own eventually has bad caking or corrosion at the contacts, and I can start the cleanup with the softest scratch brush and work my way up to the steel brush whenever needed.

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.

It should do the job but its a cheap quality item, I would not buy again. One of the 4 pens was defective.

I liked that there were refills in the package, and it seemed like a good value. I tried the brass one first and it seemed okay. The fiber brush, which was the reason I bought the set, immediately pushed out the back on the first pressure. I didnt get to scratch even once with it. I ended up buying a eurotool model - dont waste your money here, get the real thing. I returned this. At least their return process was fast and easy.
