Pro Grade - Acid Brushes - 36 Count 3/8 Inch Boar Hair Acid Flux Brushes

Standard acid brushes. Some of the hairs will fall out but at this price, who cares. Good value.

as advertised...good price and quality

Not much to say. They brush on flux. These are like the ones that you can get at any hardware store, jut less expensive. Worked like expected.

They shed bristles a lot. I wanted them for cleaning solder flux from circuit boards after repairs with isopropyl alcohol, but the bristles they leave behind make them useless for my purpose.

I am a high school stained glass teacher, and these are my go-to brushes for flux. We go through a lot of them, and the handles rust, but we get a lot of life out of them before they die. You can extend their life by soaking them in a rust remover or use steel wool it to remove it.
