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 brass and steel are simply too soft to be useful for what you would use it for. The two stars were removed because I had to open all of them to clear out extra plastic in the threads otherwise they were impossible to use.

Great little brushes

Good set of brushes. Hold up well.

Awesome set of brushes!!!

They came apart before I used them the first time.

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.

Bought them to use on a scratch board for art and they work great for that.

Love the brushes themselves, but the package could be better. Im constantly chasing after them, because they slip out and slide all over the place.

Product is very useful.
