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

very cheaply made

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!

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.

For what Im doing it works great

This product was not capable of doing gradual whiteout or whiteout period and that is what it needs to do

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

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.

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

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.
