So this really is a CHI curling iron AND flat iron, you'll never need another tool. Plus, it's digitally controlled - so you can set your temperature for all hair types. It doesn't get any easier than this! Farouk CHI changes the face of the hair styling industry again with the CHI "2-in-1" Ceramic Auto Digital Curling & Flat Iron. This styling hybrid combines the best of both worlds. Use it just like a flat iron with 1" plates - flat surfaces make hair straightening easy. Or use the lock-in button to lock the plates together - and you have a 1 1/4" barrel curling iron for beautiful curls and romantic waves.
