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

Extremely poor quality and about useless. Bad grip. Bad bristles on all of them. Already tried to use them therefore cannot send back regretfully.

very cheaply made

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

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.

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

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

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.

I really only wanted this for the brass and fiberglass tools, but the extra inserts were worth buying the set. This allows me to get the final detail done on ancient coins before waxing, and allows for more precise cleaning.

metal finish

This was exactly as expected and works well.
