The Tao Ma 'Rollphone' is the smallest phone to run on AA batteries, which prolongs use without any hindrances.

The Tao Ma 'Rollphone' not only takes on a cylindrical shape, but also features a flexible display that conveniently rolls up into the main body. This allows for easy storage in pockets and bags. The screen can also expand to accommodate for video chats.
