HAIRBEAURON 4D Plus straight hair iron equipped with Bioprogramming technology. - Brand: HAIRBEAURON - Model Name: 4D Plus - Type: Straight Hair Iron - Features: Bioprogramming Thank you for viewing. As stated in the warranty, I purchased this at a beauty salon last December, but I couldn't get the hang of using it, so I'm putting it up for sale! I heard that this iron doesn't damage the hair, so it's safe to use, and it's a top-class iron that makes your hair shiny when heat is applied! I think the purchase price was in the 40,000 yen range! I've used it about 3 times for practice, and it's a used item, so please understand and purchase it. Thank you.
