Review on Variety of Colored Fiberglass Scratch Brushes by Paarvin Freedman

Works incredibly well for cleaning contacts in old video games (NES, SNES, N64). Just use some IPA and gently wipe away the dirt. Keep away from the solder mask or you will remove it. The brush I received is exactly as pictured, including the word "Germany". The swivel mechanism isn't very smooth, which is a bit disappointing for the price, but overall I'm happy with it.
