Face

The face is designed by combining a USB flash drive and an LED light, using the USB output as a cheeky tongue.

Although it contains a battery, it can be charged when the USB storage is in use without any extra effort on the users part.
Not only providing the convenience of two useful devices in one easy to carry product, it also eliminates the need for disposable batteries making it that a little bit greener for the environment.
