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

Maybe the steel and brass pens are.. Ok.. Kinda.. But the fiberglass does nothing, Nothing at all. Wont even scratch a PCB. Youll regret the purchase if PCB solder mask removal is at all why you are purchasing,. GOOD LUCK.

This is a great little set. I only needed the wire brush but I have used the copper as well. Cleaning the rust off the Allan heads on my bikes is tough. Steel wool only goes so far. This little beauty fits right in there and makes a long job take mere seconds. Time will tell on durability, but all wire brushes do wear out. This set has been a major time saver and I know you won’t be disappointed with the purchase.

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

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

They looked great. Concept is wonderful, but quality: epic fail! Each one them fell apart within moments of the first use. The actual handles are not glued together properly. Poor control of brushes...they just fall out. The best part about the purchase was the plastic pouch they came in. It was the only thing that did not end up in the rubbish!

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

The fiberglass one is the only one I have used so far. Perfect for cleaning enameling after getting fingerprints on it and before putting on another layer of glass enamel.
