This is a straight hair iron that uses Bioprogramming technology and allows for temperature adjustment from 40 to 180°C. I purchased it two years ago and have been storing it at home. I cut my hair short soon after buying it, so I haven't used it much, and I think it's in good condition. Original price: ¥49,500 - Model name: HAIRBEAURON 4D Plus - Temperature range: 40-180°C - Technology: Bioprogramming Thank you for looking.
