This High-Quality Brush Kit Includes 5 Brushes for all of your detailing needs. Made with 100% Natural Boar Hair making them long-lasting and extremely efficient. Firm enough to remove dirt and grime but soft enough to not leave swirls and scratches on your wheels and paint. Used for wheel and interior cleaning, our brushes are the perfect tool for those tight spaces and can be used regularly with high-octane cleaners. Unlike synthetic bristles, these natural hair bristles will not shed in clumps and hold onto soaps much better. The Brush Handle is completely solid which prevents water from being trapped in the handle over time, eliminating the need to constantly replace them.
