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.

These pens worked exactly as I expected, but I was a little disappointed as one of them fell apart as soon as I took it out of the package to use the first time.

Awesome set of brushes!!!

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

Just what I wanted. All as pictured/described.

All the brushes work as intended. Ive used the fiberglass for cleaning corrosion off of electrical contacts, The nylon one for general cleaning, The brass for getting gunk out of metal parts, The steel for removing rust spots. An improvement that could be made: a plastic tray holder instead of the flimsy pouch. Would just fit better on a workbench or in a toolbox.

Useful product and it arrived quickly

they look pretty flimsy for 13-14 dollars. not to impressed so far but i just got them. brush end is about one quarter inch diameter and extends to around 3/8 inch in length.

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.
