This brush is a true handy device for those involved in the industrial and scientific fields. The bristles are tough, yet delicate enough to not damage the soldered materials. It helps achieve a smooth, polished finish for a seamless joint.
Use some of these brushes to clean circuit boards we are working on in our engineering department. Ordered some for the office here at home. Received parts faster than expected and They did exactly what I had in mind, you can't go wrong with this product.
