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

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.

Was looking to replace fiberglass pen from as far back as Radio Shack. Liked the pen function so decided on this set. Metals (brass and steel) are too thin to be practical.

Really useful little brushes. The bristles extend out about 1.5 inches for a softer brush, or keep it short for stiff bristles. Used it to clean some minor rust and it worked beautifully. Had a small problem with my order but seller responded right away & took care of the problem. Good product and excellent customer service. A+

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

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

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.

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

This is exactly what I was looking for. the range of stiffness is perfect from the very gentle but still fairly stiff fiberglass and nylon, up through brass and steel for increasing scratchiness. Only used this first time, but they worked very well: definitely goes into my toolbox.

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

The brush set is okay. However the steel brushes quickly became detached from their base, and now they just fall out whenever the brush is used to clean corrosion. I have to replace the steel brush pen, but will use a different brand/model
