• Always clean! Hand washable!
• The USB battery is neatly stored in the inside pocket.
• Convenient USB connector (USB is used as the power input plug). Convenient since you can use a USB power source or mobile battery.)
• Power switch at a glance (The power can be switched on/off and the temperature can be adjusted in three steps with one switch. The color indicates the set temperature.)
