Upgrade curling iron for long hair: The special extension design makes hair easier to curl than shorter styles. Can be used as an alternative to heating when the curling iron is very hot by using a new curling iron. Perfectly compatible with supersonic hair dryers: Versatile 2-in-1 hair dryer accessories specially designed for supersonic hair dryers (not included). Easy to install: The left and right curling irons are easy to install and remove, meeting different styling needs and making your hair healthier, more natural, and longer-lasting. Upgraded adapters are easier to use. Supersonic 2-piece curling iron: 1 curling iron, 1 adapter. Turn the curling iron clockwise (or counterclockwise) to make it flexible and maintain the hairstyle for a long time. Things to note: 1. The curling iron is very hot during use. Please do not touch it directly with your hands during use. 2. Do not use a single curling iron for a long time to avoid damage to the hair dryer due to high temperatures.
