The Tool Science Professional Digital Nano-Silver Flat Iron (1 1/4 Inch) uses nano silver's unique properties to enhance healthier hair, leaving it smoother shinier and more manageable. The Nano-Silver Digital Flat Iron uses an advanced microprocessor and ceramic heaters for flash-quick heat up and simultaneous heat recovery to prevent plates cycling from hot to cold. The high performance nano-silver tourmaline ceramic plates emit ultra high, even heat with no hot spots to protect from heat damage and enhanced healthier hair. A LED temperature read out provides accurate, real-time heat information. The wide 1 1/4 inch floating plates design is ideal for ease of styling on thick, long hair. Includes an auto-shut off program that turns off the iron automatically after 60 minutes and automatic dual voltage for global use with no converter required. Heat range from 300°F to 450°F. Why Nano-Silver? Today's science focuses on Nanotechnology. It is the technology of creating billions of particles from one particle to magnify the performance, improve functionality and uniformity of a material - in this case silver. Nano Silvers unique properties enhance healthier hair, leaving it smoother, shinier and more manageable.
