— hair curler, consisting of two cylindrical working surfaces, each with its own heater.The design of such nozzles can vary; some models have a distinctive "fork" shape with teeth of different diameters, while others feature each cylinder on its own half of the tongs, and when closed, the heaters are positioned side by side. In any case, these nozzles offer interesting additional features not available with more traditional single nozzles, but the specific capabilities can differ based on the design. For instance, a "fork" shape allows the creation of zigzag waves, and using a clamp, waves with uniform volume and size can be formed.
