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 300F to 450F. 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.
