If you wanted to give someone a present and it was going to be a brush, get this wire brush. How often have you read some instructions that say “get a stiff brush…” or “using a wire brush, gently….”. And there is never one to hand. They can be used for whatever you need but personally I think they are a small spark plug brush. Yes, you could use them a suede brush (but not if you’ve just cleaned your spark plug with it). They’re 22cm long (8.5 inches) and will fit in your ‘junk drawer’ fine.
