The Marcel Iron. It's the pro favorite for forming snappy curls, loose waves, and gentle bends. It speeds up styling time, so it doesn't take hours to achieve the Instagram-worthy looks you love! How could a 24k gold surface be anything other than invaluable? The gold plating on the gold marcel curling iron's barrel is a superb heat conductor that distributes heat evenly from end to end, so each hair is perfectly waved or curled. This collection features HOT TOOLS' proprietary Pulse Technology.
