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

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

These work great for both cleaning and creating. I use them to clean textured clay rollers that get dried clay in the cracks. I also use them to purposefully cause texture or distress to miniatures or dioramas. Four different materials for various uses, they work well.

Looking for burnishing brushes for various shop use

They came apart before I used them the first time.

I use these to repair circuit boards. Nothing else will do the jobs of removing foreign objects, old flux etc.

These are being used as one treatment when removing encrustations from ancient coins. They are used with little pressure in a circular motion and work very well.

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.

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.

This set is fantastic! If you work with electronics, even occasionally, these are a major help. Great for removing small corrosion, rust spots, exposing copper on circuit boards. Just awesome.

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