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

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.

They came apart before I used them the first time.

Great little brushes

A must have for any customizer in the diecast hobby. I actually use all 4 and work perfect

Works as described. I mostly use the fiberglass pen on motherboards and it barely flake off any fibers, does an impressive job being accurate

These work great for removing paint from small statues with fine detail.p

This is great for cleaning electrical contacts and small connectors found in home theater/audio systems.

These work great when I’m building and repairing small electronic devices.

It is apparent when opening these that they are the lowest grade products of their type. In the first set I received, the Brass Bristle mechanism didnt push up. So I ordered a replacement. The replacement came today and now I see that the one labelled Steel Bristle is actually not steel. It is a second nylon or fiberglass bristle. I am debating whether to even bother ordering a replacement. Just be aware that they are of extremely low quality.

They couldn’t scratch an itch let alone any metals. Don’t waste your money.
