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

Works just like I needed them to

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.

Useful product and it arrived quickly

These are well made and have lots of uses, but I was hoping the fiberglass pen had stiffer bristles like the one I bought years ago at a hardware store.

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

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.

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.

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.

Got this to clean up an restoration project. After using to clean up the original hardware (which had been soaked in cleaner) the 2 I used fell apart after 1 use.

Use them to clean our Pax 3 & grinders. Works great because they are adjustable so it can be stiff or soft depending on what youre cleaning.
