Thank you for viewing. This is a straight hair iron, the main unit only. Please see the images for details. The temperature rises without issue. However, after reaching the set temperature, the temperature may gradually decrease, although the display doesn't change. Therefore, I'm selling it as junk! If this happens, turning the power off and then on again will raise the temperature. Since it often can't be used stably, how about using it for wig styling, etc.?
