Review on 100 Extra Fiberglass Scratch Refills BRS 290 01 - Ultimate Solution for Scratch Removal by Trey Harvey

Good quality. Fits perfectly on my scratch brush handle. This is a thin brush so your handle must have a spring loaded collet to hold this brush. You move it under gravity when the button on the opposite end of the handle is pressed. If you have a pivoting handle to advance the brush, you most likely need larger diameter brushes and this replacement unit will not work for you.
