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 for both cleaning and creating. I use them to clean textured clay rollers that get dried clay in the cracks. I also use them to purposefully cause texture or distress to miniatures or dioramas. Four different materials for various uses, they work well.

good for getting into tight places, dont know if I can refill the brushes ?

Don’t expect to get extended use, as items are smaller then needed

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.

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.

works great but wears down fast

Use them to clean our Pax 3 & grinders. Works great because they are adjustable so it can be stiff or soft depending on what youre cleaning.

Good set of brushes. Hold up well.

Great product

Great set of brushes. Case is cheap and horrible but the brushes work great for scuffing parts and getting corrosion and solder mask off of pcb boards
