This is a mini hair straightener. It's about 15cm long, making it easy to touch up your bangs or any areas of concern while you're out and about. Please note that it cannot be charged. The temperature can be adjusted in three stages: 190/140/100 degrees. I've used it a few times, and there are some areas where the color has changed slightly. I will also ship the included TYPE C cable. *The ruler used for size comparison is not included.*
