Comair Wooden Paddle Brush to 24centymentrowa, a pneumatic brush for normal and thicker hair, featuring natural bristles and nylon pins. This medium-sized, professional brush from the German company Comair is made from natural beech wood. Eleven rows of pins are made from natural boar bristles and reinforced with nylon detanglers. The bristles are set on a cushion that absorbs pressure, preventing skin scratches. Very solidly and precisely finished. A combination of high quality and affordable price. The holes in the cushion are responsible for air release during pressure. This is not a manufacturing defect or a flaw in the brush.
