This case gets its name 'Light Tube' because the edge of the case flashes when you receive an incoming call at night‎.‎ The sides and the back of the shell are transparent that not only protect your phone from dust and scratching‎,‎ but also present the original beauty of your iPhone‎.‎ While the clear PC shell provides scratch resistance to the rear and sides of your phone‎,‎ a piece of mini USB charging cable is attached around the protective shell which also provides the maximum convenience for you to charge your iPhone everywhere‎!‎

You can take the attached mini USB charging cable with your iPhone everywhere that you will never worry about forgetting to carry it or the power of your iPhone running out‎.‎
