I was in Korea recently for just over two weeks and during my time there i noticed a certain phenomenon in the cafes. Many girls were wearing these curlers and when removed their bangs are miraculously perfect. Curious, I enquired about them from a Korean blogger friend and she told me they were extremely popular in Seoul at the moment. She also told me that the reason they actually work is the fact they heat up!
Yes they heat up. As a matter of fact, they are USB powered!
Needless to say, i had to find out what the fuss was.
