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

Maybe the steel and brass pens are.. Ok.. Kinda.. But the fiberglass does nothing, Nothing at all. Wont even scratch a PCB. Youll regret the purchase if PCB solder mask removal is at all why you are purchasing,. GOOD LUCK.

Great for the money

Nice set. I havent used them yet, but glad to have when I need them.

They managed to help me get a car touched up and performed well.

Yes you have it, and when you need one, you can use it.

The header says it all.

good for getting into tight places, dont know if I can refill the brushes ?

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.

Got the job done and delivered before promised

Typical cheaply made junk. Should only cost a buck. Way over priced
