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

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

I liked that there were refills in the package, and it seemed like a good value. I tried the brass one first and it seemed okay. The fiber brush, which was the reason I bought the set, immediately pushed out the back on the first pressure. I didnt get to scratch even once with it. I ended up buying a eurotool model - dont waste your money here, get the real thing. I returned this. At least their return process was fast and easy.

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

I use mine on my modeling/sculpting bench. They work great, and its wonderful to be able to retract and protect the bristles when not in use.

they look pretty flimsy for 13-14 dollars. not to impressed so far but i just got them. brush end is about one quarter inch diameter and extends to around 3/8 inch in length.

This whole set costs as much as one brass bristle brush on Rio Grandes website. I can use them for different projects, with the primary being the brass brush for cleaning files.

I used them for removing corrosion from leaked ni-cd batteries. They worked well.

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.

I have now tried all 4 pens, even though I truly only needed the fiberglass. The brass and steel pens hold up fine, but its not a great idea to just start scratching away at things with metal. The nylon brush is useless. You might as well get a $1 kids paint brush, because you will not scratch away anything with the soft edges of this nylon. Finally, the fiberglass pen. I was trying to remove about a 1in x 0.5in section of circuit board coating and it did NOTHING to remove that coating. By the time I scraped away the top coat with a separate, metal spudger, I went back to the fiberglass to polish. POOF. The whole section tried to disappear into the pen. Fished It out with tweezers and clamped the holding section so tight I could barely get the pen tip back on. First round back at it, a little resistance then the whole thing disappeared again. If youre going to need the fiberglass specifically, DO NOT BUY THIS PACKAGE. Spend a few extra dollars and get a quality product that will last AT LEAST a single use.
