The Andis 1" Tourmaline Nano-Ceramic Curling Iron is perfect for both curling and straightening your hair without damaging it. The curling iron has a nano-ceramic coating for an ultra-smooth finish and the barrel contains tourmaline semi-precious stones that eliminate frizz for silky, shiny hair. Quickly heats up to 450 degrees in 30 seconds, with multi-temperature high heat settings for precise temperature control for both thick and coarse hair. The ceramic barrel creates far-infrared heat that penetrates the hair from the inside out for deep, long-lasting curls.
