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

Great for woodworking Ive already given some to my friends

If you work on electronics, this is a must have.

They are of the quality that you would get as a prize from Chuck E. Cheeses.

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.

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.

I needed stiff brushes for precision cleaning small items in tight spaces. This set of brushes is invaluable for anyone who needs to clean spaces too small for regular brushes. If you have been trying to use paint brushes, you know they are too soft and flexible to be practical. Another advantage this product provides is that you and trim the length of the long brush for a new top surface. Each brush also has one replacement brush as well.

It is surprisingly difficult to find fiberglass scratch brushes for electronics. I have been using this for a week or so and the fiberglass cleans traces well and I find myself using the nylon and brass more than I expected. The nylon is good for cleaning solder joints where you need something firmer to get old flux off or baked on crud. This set came with replacement brushes, I have no idea if the bodies will last that long. As mentioned in other reviews the bodies are a little on the cheap side. For the price it wouldnt be painful if I had to buy a new set every year. It would be nice if someone would make a really nice sturdy set, something you would keep for a lifetime. One of my friends who does electronic repair has a 3/4 fiberglass scratch brush and he said it was really expensive. I couldnt find one so this will do.

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

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

No instructions. Tips seem hard to change, and unsure as no instructions.
