8 Pieces Scratch Brush Pen Set, Pen Style Prep Sanding Brush With Steel, Brass, Fiberglass, Nylon Replacement Tips for Jewelry, Watch, Coin Cleaning, Electronic Applications, Auto Body Work

The fiberglass brush worked as expected but the nylon brush was a happy surprise with how well it performed!

Using them to refurbish old lamps. They do reach nicely into tight spots.

I have used a these a few times and they done the job I expected of them. They definitely helped reaching areas that I could reach with my fingers.

Brushes are reasonable quality for price however if using these on circuit boards the stiff fiber is not stiff enough to remove conformal coatings and you need to use the brass or steel brushes. Other than the stiff fiber brush not being as aggressive as what I was used to they work fine.

Works as described no issues

I wanted a fiberglass pencil to clean electrical contacts and this set had several materials other than the fiberglass. That said, i have used the fiberglass and the steel wire variants…. One to clean a network connector and the other to clean corrosion off the contact in a grill igniter. The steel one worked great. The fiberglass is a tad soft and it does work….but i have had one in the past that was about 20% stiffer and in general was better. Overall you cant go wrong and they give a couple extra inserts. Worth the purchase!

Great for woodworking Ive already given some to my friends

Very nice set of scratch brushes. Very compact and work well.

Works great to clean watch braclets and inside the watch case.

Disappointing product. Very low quality construction. These are essentially a disposable item. Way overpriced for what this is. I expect that it will last one use. It arrived halfway to useless with white stress marks on the pens and the holder was broken at the bottom. This Belongs in the dollar store.
