This is a professional Ionic Flat Iron with slim 1'' plates. It creates smooth & silky hair while eliminating frizz. I really like this flat iron because it has 25 different heat settings so you can change it based on how your hair is cooperating or not cooperating that day. I use this with the Matrix Sleek Iron Smoother before using the flat iron on my hair. Both products work very well together at achieving straight hair that looks silky and does not look dry and brittle. Because the flat iron's plates are only 1" it makes this very easy to bring with you when travelling...all while not taking up a lot of room in your bag!
