Fiberglass Scratch Brush Pen - 3 Pack - Jewelry, Watch, Coin Cleaning, Electronic Applications, Removing Rust and Corrosion

Excellent for all cleaning purposes.

I’ve been making jewelry for 4 years and someone I follow mentioned using these so I bought them on a whim. I don’t know how I’ve lived without them up to this point! They are perfect for cleaning the inside of a bezel and I also solder gold fill, and these clean up goldfill pieces without scratches.

This brush pen is a fantastic tool for removing scratches from various surfaces. The bristles are durable and effective, and the pen is easy to use. It's a great value for the price,

There isn't really much to be said for these. They aren't overpriced and they work well enough, so I'm happy.

Easy to use

I bought these for detailed cleaning of vintage items; if you're on the fence about them but have landed here, just grab them.

While so very few people know these scratch pens even exist, everyone, and I mean everyone should own them. Anytime you have a battery that leaked in an item, these are the most effective way of cleaning the contacts before installing new batteries.This 3-pack was just a great deal!It is just that simple.

I bought these to try and clean up some PCB terminals and video game cartridge terminals and they're working really well. I've also used them successfully to get off a little battery acid corrosion.

These are excellent. The fibres are much finer than the older fibreglass erasers, much less chance of leaving scratch marks.

The media could not be loaded. This product is useless. The bristles are soft and flexible, not hard and rigid like a proper fiberglass pen is supposed to be. It might work to polish something that it's already pretty much clean, but it's useless for removing rust and corrosion.

very low quality, poorly manufactured. is barely abrasive, and loses billions of fiberglass particle as you use this chinesium. get a better, branded one. This thing is useless. pencil eraser is more abrasive than these pen.

J'ai une brosse a dent plus rigide que les 3 stylos.J'ai l'impression qu'il ont oublié de les tremper dans la résine.J'arrive même pas a faire une marque sur un papier d'imprimante tellement ils sont mou.
