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 handle is plastic, and very very easy to break. After about a minute of use, one of the handle broke and wont open anymore.

Some pieces were missing and the pen holders were all damaged on all 3 packs

metal finish

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

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

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

Fantastic idea I havent used yet seem to be a little flimsy might break easily I purchased to clean corrosion out of AAA battery compartments on camera equipment. I love the way you can extend and retract the brush Not sure how the plastic will hold up with electronics cleaner spray might melt or the metal tip hold up with simple green or other water based cleaner might rust

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!

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

One of the tools came broken right in the package, it was glued up wrong and unusable. the other tools were cheap junk that will probably break the first time I use them. poor manufacturing, bad quality control and cheap materials. Ive seen better made stuff at the dollar store.
