It's a Dyson Airwrap.

One of my absolute favorite items is the Dyson Airwrap. It functions as both a hair dryer and a curling iron. It uses hot air to style my hair and keep it smooth and tamed. On rainy days, my curls tend to lose their shape quickly, so I straighten them out like a straightening iron, while on sunny days, I curl them. It makes my hair look just like it was styled with a curling iron, giving me a truly goddess-like look. It does loosen up a bit compared to before I head to work, but that looks pretty too.
