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

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!

I didn’t know these scratch, sanding, cleanup pens existed. Wow was I missing out. They get into tiny spaces and are great for prepping something to solder, for sanding a tiny spot to paint, or taking a little tarnish off items.

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.

I bought these brushes to clean crevices and tight spaces where a regular brush wont fit. The brass and steel bristles are very weak. They are virtually worthless for cleaning. I havent tried the nylon ones.

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

What can you really expect for $4.25 each, have low expectations and just consider them disposable....

There okay. You’ll need to trim & clean them to get the right finish you’re looking for if you’re trying to remove CA glue from a plastic model.

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.

works for a few jobs then just toss them....... china JUNK ..not built to last

They are of the quality that you would get as a prize from Chuck E. Cheeses.
