I accidentally bought this, thinking it was a regular hair iron... I realized my mistake after opening the box, so I haven't used it at all. I just bought it on December 22nd (_ _*)) Please feel free to negotiate the price. ※This is an ultrasonic hair iron! It uses ultrasonic waves to break down the treatment into molecules, allowing it to penetrate the hair shaft through the cuticles for enhanced treatment effects. Cordless type.
