CHI Onyx Euroshine Ceramic Curling Iron has an ion generator that, in combination with the Onyx ceramic tube, produces twice as many negative ions. This makes the hair even smoother and shinier and the curl remains in shape throughout the day. Thanks to the extremely smooth rod, the curling iron glides effortlessly through the hair. The curling iron has a non-slip rubber handle with heat-resistant silicone, a thumb rest, a cool tip and a stand to safely store the curling iron. Thanks to the good grip, the curling iron is easy to use.
