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 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.

So I bought this because I was getting notified that my Pixel 3 was charging/connected to USB when it actually wasnt. Apparently this happens when the leads start to corrode. I bought this and use the bronze, nylon, then fiberglass brushes. Not sure which of them worked but it seems to have been fixed. Hard to see into the USB outlet so I am just going on the error messages. I will revise this rating if it didnt fix it. The brushes themselves are cheaply made but are a good value for the price

The package arrived on time and the tools were just what I needed. Thank you.

I do a lot of SMD rework and find these really handy for cleaning up copper, pads and lands. I mostly use the fiberglass brush, but the others find occasional use. Very nice set. 5 stars.

Looking for burnishing brushes for various shop use

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

Pixiss Scratch Brush Pen Set, Fiberglass, Steel, Brass, Nylon, 5-inches Pen Style Prep Sanding Brush 4-Pack for Removing Corrosion and Rust, Jewelry, Electrical Circuit Boards and Auto Body Work

Needed a fiberglass pen to clean some corrosion off a circuit board and it worked just right! Thanks again.

Just what I wanted. All as pictured/described.

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!
