The plates of this iron extend and round up the side of the iron providing constant heat on your hair when you are curling/flipping. The U Styler does it all- more effectively and efficiently. The curved side plates create perfect curls in one smooth flip while Sol-Gel technology delivers stronger plates and a smoother glide. The U Styler offers the same superior performance as all Nano Titanium Irons. A ceramic heater for instant heat-up and steady heat up to 450 Degrees F.
