Thank you for viewing the product. I purchased this after seeing YouTuber Nanako use it in an old video. I've used it a few times and stored it in a dark place. The storage bag has a little bit of dirt on it. Please refer to the photos for details. 〈Product Details〉 【16-Step Temperature Adjustment, Burn Prevention】The temperature can be set in 16 steps. Adjustable from 80°C to 230°C. It can be used for a wide range of hair types, from soft and fine hair to damaged, coarse, and thick hair. Even when the brush is hot, the red part of the brush prevents burns, so even if you accidentally grab or touch it, that part won't be hot. 【Rapid Heating, 360-Degree Swivel Cord】The MCH heater has high thermal conductivity, heats up instantly, and heats up rapidly in about 1 minute, which is convenient for mornings when you're short on time. It quickly styles your hair, preventing damage. The 360° swivel cord allows for hard movements and prevents the cord from tangling, so you can set it at any angle you like. 【Double Ion Generator, Shiny Hair】Equipped with two negative ion emission ports, approximately 3 million negative ions are released, providing a moisturizing effect and protecting the cuticles while reducing hair damage from heat. It also glides smoothly through the hair, resulting in a beautiful finish.
