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 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.

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.

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.

I would be happy to pay a little more to have a little better design. Out of the four brushes that I received, two of them failed when I tried to extend the bristles. The mechanism that pushes the bristles back and forth is a poor design. They work great when theyre in one piece. The pictures depict what happened when I tried to push the bristles out. The back end came undone.

Got this as a supplement to my other scratch brushes and they dont scratch anything all. Even the metal brushes dont remove solder mask from PCBs.

With the assorted, retractable tips, this scratch brush set handles everything Ive used it on. Good bargain.

Works just like I needed them to

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.

Not worth the money. My own fault. I should have spent the extra few bucks and bought a quality product
