I recently returned from a delightful trip to China. I had with me the most marvelous small appliance that filled the bill so satisfactorily. I wanted a curling iron for my hair with me so much that I was prepared to take along the needed adapters and converters. At the last minute I discovered a curling iron that runs on butane, obtained one, used it every day on the trip, and did not have to bother with a cord. The curling iron is called a Clicker and I highly recommend it. The Clicker was readily available at a major drugstore.
Thanks for the fine Travel Section each Sunday; I really enjoy it.
