This is a Bioprogramming curling iron. It's the 4D Slim type. I haven't used it much, but there are a few scratches and signs of use. I'm selling it because I cut my hair and don't use it much anymore. I purchased it from an official shop. It has an ID, but I haven't registered it, so I think they will handle repairs. I've confirmed that it works. I hope someone will use it. - Color: Black/Gradation - Power Type: Outlet - Function: Curling Iron Thank you for looking.
