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 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.

Would be nice to include a pencil-eraser type of abrasive and a commutator dressing stone type.

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.

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.

Works great to erase little errors in woodburning. Can pull out paint as well.

You can get into tight areas in your models.

nice set for small jobs nice variety

Product is very useful.

The red one/ fiberglass does not work in my kit. Dont know if this is normal just my experience.

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.
