From straightening to curling, the SinglePass Compact offers full styling capability in a portable size with the added convenience of a heat resistant cap for quick storage and ease of travel. This styling iron can be stored at the office for quick touch ups or inside your purse, gym bag or carry-on luggage ensuring your tresses stay perfectly styled no matter where your busy schedule or travels take you. T3 Tourmaline SinglePass Technology:Digital heating technology so advanced, it takes the conventional styling iron into the realm of artificial intelligence. Regular irons test their plate temperatures in intervals, causing heat fluctuation and damage due to over-styling. T3 SinglePass Irons have a microchip brain that constantly measures and adjusts the temperature across the plates for even heat with no hot spots and no damage the entire time you are styling. The result? A long-lasting, smooth and shiny finish.
