Think of a car with a turbo booster. With every step on the accelerator, you get a boost of power from the engine. This turbo technology was added into our Presto models. Every time the styling iron is clamped, the turbo trigger is activated and shots of heat (10°F) are released. These styling irons all reach 450°F releasing bursts of power, thereby giving better styling control. Our Presto plates have also been infused with real diamond powder which releases hair deeper into the hair cortex for long lasting styles. Turn stubborn and dry hair into sleek, shiny, and healthy hair. Presto series come in 1″, 1 1/4″, and 1 3/4″ plate sizes.
