Here is how they work: The special sectioned tufting pattern acts like 3 brush strokes in one! * As you brush your pet"s coat with the BASS Pet Groomer, the outer layer of metal pin tufts gently yet thoroughly detangles the coat, removed larger particles, and provides a gentle massage effect. * Next, the middle layer of pure boar conditions the hair by distributing natural oils, leaving a healthy shine and a protective layer over your pet"s coat. * Finally, the outer layer of wire pins passes through the hair once again to smooth and separate the conditioned hair. * The final result is a clean, healthy and luxurious coat that other brushes simply can"t provide. All handles are made from natural, earth-friendly bamboo.
