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

Needed a fiberglass pen to clean some corrosion off a circuit board and it worked just right! Thanks again.

This has a nice variety of bushes of different materials. I never used a product like this before and may have had too high an expectation for its effectiveness. It helped but didnt do the job I had hoped for. It is worth the money to have on hand.

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

Great value

I used them for removing corrosion from leaked ni-cd batteries. They worked well.

I use these to clean electronic parts and repairing vintage toys.

Great product

I got this because I had 2 rusted chips on my jeep and the recommendation was to use the fiberglass pen to clear the rust. I ended up getting the jeep oem touch up kit and the scrub tip on that combined with an exacto blade tip did a far better job than this one. If you’re getting it for some other purpose I’m sure it does fine but if you’re trying to clear rust from a paint chip then save the money

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.

Useful product and it arrived quickly
