A conceptual mobile phone that mimics a matchbox, with the most commonly used keys set on the outside. The numeric keys can be revealed by pulling it out like a matchbox. This mini personal mobile phone, designed by Lv Zhongfang, can be easily placed in a pocket, but can extend to a more practical size when needed. The modular design allows the screen and phone keyboard to be separated or combined, and its solid feel can be compared to the analog mobile phones of yesteryears.
