Before, when I traveled with my family, I found a hair dryer that I had never seen before in the public bath at the accommodation.
The dryer had no blades and had a hollow in the middle. I’d seen a fan without a blade on a TV commercial before, so I knew it was Dyson.
The name of this dryer is Dyson Supersonic Ionic Hair Dryer. The price is quite high at USD470 (tax included). When I tried using it, I felt that the wind power was stronger and the hair dried faster than the one I used at home.
This dryer is registered under Design Registration No. 1513825.
