Heat Brush Iron - Black Uimuio Only used twice for testing, so it's in beautiful condition! Please refrain from purchasing if you are overly concerned about minor details. I will wrap it in bubble wrap for shipping. 【Negative Ion Function & Heats Up in 45 Seconds】 This hair iron brush nozzle releases tens of millions of negative ions per second, smoothing and softening hair while preventing static. Adopting advanced heating technology, it can reach a maximum temperature of 230°C in 45 seconds. It heats up quickly, reducing hair damage from temperature changes. Even on busy mornings, you can quickly achieve your ideal hairstyle. 【16-Level Temperature Adjustment & Temperature Memory Function】 There are 9 levels, adjustable in 10°C increments from 80 to 230°C, accommodating a wide range of hair types (fine, thin, coarse, thick). From natural straight styles to elegant curls, this one tool allows for versatile styling. The hair iron has a convenient temperature memory function; when you turn it on again in the OFF blinking state without unplugging the cord, the previously set temperature is automatically remembered, so you don't need to reset the temperature.
