I have to say this product is excellent and better than other products on the market. The bristles are a bit stiffer than other brushes, which gives them an advantage as they resist scratches well. I use replacement tips for my original Radio Shack scratch tool and buying German made products is a luxury these days. The brushes are great for finishing work and I use them to polish off the oxidation on HO locomotives and also to get the tracks nice and shiny before soldering the track work on my breadboard. some very old coins to remove sand and get fine detail on the surface. Also used on PCB traces to remove oxidation so you don't always have to use solder paste or rosin before soldering.
