Unique duo-pin design features both long and short durable angled teeth. Classic curved back design is excellent for removing the most stubborn mats and tangles, even in difficult to reach places. The Universal Duo-Pin slicker is ideal for use after bathing while blow drying the coat. Use light, long strokes with and against the direction of coat growth. Brush slowly to avoid static build-up. If the coat is matted, use the Universal Duo-Pin slicker in combination with a Matbuster de-matting tool. To prevent mats and tangles, the dog's coat should be regularly bathed, treated with a conditioner and brushed daily.
