There is nothing to beat real rice root as a deep cleaning mud brush, but this
look alike comes a good second at a lower cost. The tufts are made with nylon
which absorbs water, and unlike (much cheaper) polypropylene that means it
carries soap and water from the bucket to the horse. Nylon has the added
advantages of being very durable, and won't deteriorate if left damp. And at such a great price, it's perfect for all your grooming needs.
