Fiberglass Scratch Brush Refills, 24 Pack, Medium, 1-1/4 inches

I use these for jewelry cleaning for the most part but also have another brush handle at work for cleaning little spots on sensitive equipment or even spots on not so sensitive equipment but places you can't get into with normal means of cleaning. Worth every cent! I used to just buy a new 3 pack everytime they ran out but with the abrasive and\or chemical makeup of the jewelry cleaner it eats right through the fiberglass. A normal 3 pack goes for about 9 bucks plus shipping for this pack 24 (eight of the other option equaling 72+s\h to 100+ dollars depending on amount bought in each shipment. One at a time being nearly 140$!!! So yea like i said before WORTH EVERY CENT! I would recommend buying for the red handle ones shown in pictures and description so you know they fit unless you know the size of those and have one like it. They're usually pretty standard size.

These are great for cleaning, electrical contacts, anything that has mild corrosion

I use these for cleaning battery contacts or other small items needing a mild abrasive that are in a tight corner etc. You do wear them down pretty fast, but that’s why you get the big box! They also fit a different brand of holder so I am happy. Wear a face mask and goggles as fiberglass splinters are no joke. Wash your hands too!

Great for cleaning small electrical contacts and plugs, used with pen style holder.

Quality could be better. Needs flexibility but with some stiffness
