Innovation Air Flow K-245 is a revolution in stubborns for professional use. Its advantage is a specially designed design that makes it unique: unlike ordinary stitches that open and close with inevitable loss of heat. The novel is equipped with a central opening through which the hair is shaking. This function ensures a constant optimum temperature during straightening with excellent, long-term results, and the Air Flow activated system provides additional air flow to protect the hair from drying and helps to close the hair drying. Air flow cannot be felt by hand, but the effect is visible when the device is used. Since no pressure is required to close the stubborn, your hands are now free to move through any stream, large or small, which makes perfect smooth or natural waves much easier and faster. An innovative solution that facilitates the laying and does not load the wrist. The sliding pen and burn protection provide maximum comfort during use.
