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

Used them extensively on model railroad layout.

A combination of tools allowing you to remove minor surface contaminants as well as corrosion to keep that perfect contact for batteries. Good for removing surface corrosion for volume sliders, battery contact springs and surfaces. Different materials allow you to select the abrasive brush desired.

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.

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

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.

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.

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.

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
