Nano Titanium is an exceptional conductor of heat and maintains stability in ultra-high temperatures. Negative ions are emitted for faster straightening and locking hair's own natural moisture. The extra-long 5-inch plates reach up to 450ï3⁄4°F and allow for wider sections of hair to be straightened, boosting speed and effectiveness while eliminating hand fatigue and increasing styling flexibility. The ultra-thin profile of these high-tech irons makes them exceptionally lightweight and easy to use, with housing made of Ryton to resist high heat.
