Features: This is a very nice set of three different (types of bristles) brushes. The different types of bristles allow you to use them on different types of smaller items depending upon your needs. These brushes are great, different bristles for different needs. You can use the nylon brush for delicate jobs and the brass brush works great for getting off corrosion.The rubbery grips improve the comfort of using these, especially for longer projects or anything where you're applying a bit more elbow grease. Perfect for smaller cleaning tasks, including more detailed work. Good for parts and tool cleaning but on the small side for larger projects.
