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!

very cheaply made

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

Très efficace pour nettoyer les petites pièces qui étaient rouillées

Not high tech, but if you finish soft metals youd be surprised at how these finish metals. Better than sandpaper, delicate control

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.

metal finish

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

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.

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