Andis 37530 Tourmaline Nano Ceramic Curling Iron This high style 1 1.5 inch curling iron is perfect for all hair and styles. Crushed from precious gemstones, the tourmaline crystals emit negative ions that quickly seal the cuticle layer and eliminate frizz for smoother, silkier hair. Nano ceramic with its ultra smooth finish minimizes the friction, and delivers far infrared heat. It penetrates the hair from the inside out, for deep, long lasting curls. The fusion of nano ceramic and tourmaline curls hair in less time and without typical iron damage. Hair is left softer and shinier. You can flip, shape, control and smooth hair with a single product. The maximum temperature of 400 degrees allows you to really lock in the curl and create professional results at home. The inferno red exterior looks great while styling or resting on your countertop. Worldwide dual voltage, auto shut off for safety, tangle free cord, and fast heat up, are features that all women need in their styling appliances.
