Review on 300-Pack Steel Wire Brush Set With Rotary Tool Accessories - Rocaris Wire Wheels, Pen Brushes Kit For Improved Cleaning And Polishing by Yuri Rochelin

These things fall apart instantly on use. The metal shards shoot out and hit you in face and body. They shards are very difficult to remove from skin and clothing. They end up everywhere. I had several stuck on my face arms and feet where the were tracked in my house and shower. If you don't wear eye protect you will most definitely be severely injured. They should be removed from the market immediately. If you really need to use these, do yourself a favor and buy the original Dremel ones.
